Jean-Lou Pierson is a Research Engineer in the Fluid Mechanics Department at IFP Energies nouvelles (IFPEN). He received his PhD from the Institut National Polytechnique de Toulouse (INPT) in 2015. His research focuses on the modelling of dispersed multiphase flows, particularly anisotropic particles and droplet suspensions . He investigates hydrodynamic interactions between inclusions, their dynamics in turbulent flows, and the scale-bridging approaches required to represent these phenomena in engineering models. By combining interface-resolved numerical simulations, theoretical analysis and averaged formulations, his work aims to develop physically based closure laws for multiphase-flow simulation. Applications include liquid-liquid extraction, gravity separation and pneumatic conveying.
