Postdoctoral (m/f/div): bio-inspired robots to understand individual decision-making in fish school
Postdoctoral (m/f/div): bio-inspired robots to understand individual decision-making in fish school
Company profile: - The offer: Recently, biologists and interdisciplinary teams are using robots as viable platforms to understand animal behaviour. This strategy offers a suitable alternative to traditional biological methods, which have severe limitations, including the feasibility to minimize confounding influences and isolate effects (e.g. the effects of the experiment and the experimenter on the study animal), and other limitations imposed by the behaviour of the animals, etc... For example, a fish-like robot can greatly help biologists collect in-situ data on fish schooling behaviour with limited interferences from human or other factors, explore potential hydrodynamic benefits among individuals excluding psychological effects, and understand mechanisms in collective motion by including the robot in the loop of collective animals. In this project, the candidate will construct and employ a variety of bio-inspired robots, including physical, numerical, and virtual robots, to study individual decision-making, sensory-motor control in collective motion, swarm robotics, and other systems. They would work closely with and/or directly contribute to developing the immersive virtual reality platform with virtual robots and the flow tank platform with physical robots. The experimental component of this project will be controlling those bio-inspired robots acting as neighbours to interact with the live focal system to transfer or receive specific information (e.g. visual or hydrodynamic clues).Requirement: We are seeking an exceptional and highly motivated researcher with a background in several of the following topics: Advanced design and control of mechatronic systems Advanced control of robotic fish Robot operating systems (ROS, ...) Sensor fusion Modeling and control of under-actuated, multi-body systems computational fluid dynamics (CFD) particle image velocimetry (PIV) Deep/reinforcement learning Evolutionary game theory.Organization / University: The Max Planck Institute of Animal BehaviorDeadline: -

M/W Postdoctoral Fellow Position: An Experimental Study Of Hydrogen Combustion
Company profile: CORIA is an academic research laboratory, joint research unit (UMR) attached to the Institute of Engineering and Systems (INSIS) of CNRS, the Université Rouen Normandie and INSA Rouen Normandie.The offer: This experimental study will be done in two steps. Firstly, Chemiluminescence imaging will be implemented in one partner's R&D center in a real-size burner configuration at nominal operating conditions. Modification of flames structures with the variation of H2 content in natural gas – hydrogen blend will show the changes in turbulent flame stabilization modes and heat source locations when progressively transitioning fuel composition from natural gas to hydrogen. In the second part of the study, a similar burner configuration will be downscaled at moderate thermal power (around 25 kW) for the lab-scale experiment in CORIA lab. Flow velocity measurements by Particle Image Velocimetry (PIV) will be performed to determine aerodynamics features at the burner exit and in the flame. OH Planar Laser Induced Fluorescence (PLIF) will give instantaneous images of reaction zones in the flame. All the results and their analysis will point out in details the turbulent flame stabilization process and its variation with CH4-H2 blend composition up to pure hydrogen flame. The impact of oxygen addition in air will be also studied with similar methodology and optical diagnostics. Lastly, these results on flame characterization can be linked with the study of the impact of hydrogen on products quality that will be also realized by other partners within the HyDéTOP project.Requirement: Applicants will hold a PhD degree in Physics or Mechanical Engineering. Strong background and experience in experimental study in fluids mechanics (reactive or not) and/or optical diagnostics will be considered. Ability to work in a team on collaborative projects.

Postdoctoral: Development of Lagrangian tracking techniques (LPT)
Postdoctoral: Development of Lagrangian tracking techniques (LPT)
Company profile: The CNRS, within the Pprime institute, based at the Futuroscope, this post-doctorate position is working on a new prototype of innovative gravity filter, as part of a European Grinfil contract. The offer: The agent's main mission will be to develop and finalize a Lagrangian tracking technique to measure the velocities of particles or bubbles. This volumetric technique based on laser or diode volume illumination and several cameras will allow with a good resolution to follow the trajectories. The objective of the work that the candidate will have to provide is to reconstruct a three-dimensional displacement field of particles from images of these particles at short time intervals and in different directions (typically 3). The concentration of particles will be as high as possible. For this, the candidate will rely on existing camera calibration and triangulation libraries, developed in C++. He will have to develop a particle matching algorithm on several successive instants in order to obtain particle trajectories. The main difficulty lies in the fact that particle localization errors are amplified during the matching process, leading to the appearance of "false" particles and the disappearance of "true" particles. This is all the more true when the particle concentration is high. The candidate will therefore have to introduce regularization constraints on the displacements to reduce the uncertainties on the location of the particles and allow the verification of the continuity equation. He will also have to take into account the particles that enter or leave the measurement volume. The developed algorithms will be validated on synthetic data and applied to experimental data already obtained elsewhere. A comparison can be made with commercial software. The candidate will be expected to perform the following activities
- Developing a Lagrangian tracking technique with existing tools and libraries in the team
- Validating the algorithms on synthetic data - Applying the method to two-phase measurements in the pilot developed for the project
- Working in close collaboration with the scientific leader of the project
- Validating the work in conferences and scientific journals

Postdoctoral: 3-year in How do copepods react to a turbulent flow?
Company profile: The ‘Institut de recherche sur les phénomènes hors équilibre’ (IRPHE) is located in Marseilles, France. IRPHE is one of the leading French laboratories in fluid mechanics, with a strong interdisciplinary history.The offer: The objective of the project is to link the flow information sensed by copepods to their motor behavior. For this purpose, we will track copepods in different flows. The experiments will be performed in simple model flows (shear flow, Taylor-Green vortices), as well as in a turbulent flow (von Karman flow). The challenge is to infer, from 3D tracking data, a behavioral relationship between the local flow sensed by the animal and its action. This behavior will be compared to what is expected from a copepod model trying to catch a prey or escape a predator.Requirement: Candidates should hold a PhD in fluid mechanics, soft matter, or biophysics, and have an outstanding track-record.

Postdoctoral: Trapping of heavy flexible disc within vortical flow
Postdoctoral: Trapping of heavy flexible disc within vortical flow
Company profile: -The offer: Particle clustering is a key parameter to model aggregation in turbulent flows. For heavy spherical particles, it has been shown that this phenomenon is mainly due to centrifugal forces which expel particles form high vortical regions. For thin flexible particles, the situation seems more complex. Their deformability allow the particle to wrap around the vortex core to follow the streamline. This shape is related to a difference of pressure from each side of the particles, the pressure being higher farther from the vortex core. This pressure difference is responsible of a net force that push the particle toward the vortex core. The balance of this net force and the centrifugal force might be at the origin of a new equilibrium distance from the vortex core. The aim of this project is to characterize this phenomenon both theoretically and experimentally. The flow will be generated in the Cube facility, already used in previous studies on Lagrangian turbulence. However, the forcing will be different and a series of experiments will be performed at the beginning of the project to characterize accurately this new flow. This will be done using classical Particle Image Velocimetry or Particle Tracking velocimetry methods. Then, a systematic study of the dependence of the equilibrium radius on the particle density and flexibility will be lead. Finally, our results will be compared to the theoretical model derived in parallel with F. Candelier.Requirement: The duration of this proposal is of one year. The hired student will have a PhD in Physics (Fluid Mechanics) and preferentially have some expertise in particle tracking. She/He will be in charge of the experiments: to manufacture particles, to run the experiments and to post-process the experimental data at IRPHE. She/He will also work in collaboration with F. Candelier to derive theoretical model of this phenomenon. She/He will be host at IRPHE and, as funded by the Institute of Mechanical Engineering of AMU, will have to supervise undergraduate students for 2 months and/or give lectures within the master Fluids and solids.Organization / University: Aix-Marseille universityPosted date: 06/10/2021Deadline: -

Company profile: -The offer: The project will investigate how the release and wider dispersal of fines generated during blasted rock dumping operations (from road and rail tunnel excavations), and their potential environmental impacts within the fjord, can be minimised. The PDRA at Dundee will conduct scaled physical model experiments to establish dumping procedures that are most effective in depositing the blasted rock fragments to the seabed, while minimising wider fines dispersal from the margins of the coarse particle-laden plumes generated. The project will thus target improved physical understanding of the fluid dynamics of rock dumping operations, both within the vertical pipeline arrangement into which the rock fragments are dumped and following their release at depth into deep fjordic waters. Your priorities will include:
- Collate and analyse previous literature on the physical characterisation of coarse particle-laden plumes and dumping of rock rubble in deep water.
- Design and execute scaled physical modelling experiments aligned with the scientific, environmental and commercial objectives outlined in the project description.
- Conduct data post-processing and analysis (i) to develop improved parameterisations for polydisperse sedimentation and size-segregation of the rock fragments during dumping, and (ii) to inform improved dumping strategies to minimise environmental impact.
- Assist on external collaborative research activities (e.g. steering group meetings, knowledge exchange) and the provision of strategic research outputs (e.g. journal papers).
