The Toulouse Institute of Fluid Mechanics (IMFT), the Chemical Engineering Laboratory (LGC), and IFP Energies nouvelles are pleased to invite you to the final MUSCATS workshop, which will be held at the IFP Energies Nouvelles – Lyon on 18-19 March 2024
Even if little studied, unlike gas-solid fluidized beds with spherical particles, liquid-solid fluidized beds are nevertheless widely used in a variety of industrial processes dedicated to oil and biomass exploitation as well as water treatment.  Thanks to a better understanding, they can be optimized for the benefit of energy transition.
The ANR funded project MUSCATS (MUlti-Scale modeling of fluidized/ebullated bed reaCtors involving Anisotropic parTicleS) aims at modeling liquid-solid fluidized beds of anisotropic particles thanks to a multi-scale approach.
During this event, the most important results of the project will be shared in the presence of researchers from the industrial and academic worlds working on fluid-solid fixed and fluidized beds, anisotropic particle dynamics, turbulent flows with complex particles, and dense particulate flows.
