Renaud Ansart

My research activities focus on particle gas flows, particularly fluidized beds, used in industrial processes for energy conversion. In order to optimize and design these processes, my experimental and numerical approach is from lab scale to industrial scale

Concentrated solar power with particle receiver (European Projets CSP2 and Next CSP)

Inter-Particle short and medium-range Action Forces in fluidized bed reactor: experimental and numerical coupled analysis (ANR IPAF)

Developpment of Electrical Capacitance Volume Tomography (ECVT) in fluidized bed

Development and application of Euler-Euler approaches (NEPTUNE_CFD code) for particle-laden flows in dilute and dense regime

Modeling and 3D simulation of reacting fluidized beds at industrial scales (such as solar receiver, coal combustion chamber, polymerization reactor, Fluid Catalytic Cracking risers, ….).
