Reactive Fluid/Solid Flows 

title Left  Reactive Fluid/Solid Flows

 

Liquid / Solid fluidization of 500 particles at 4.5 Umf coupled with temperature (fixed particle temperature).

Contours of Q-criterion (norm : 10/1000) colored by velocity. Resolution : 50 points / diameter, 128 procs, 2 months.

 

 

Laminar flow through fixed bed of 25 catalyst particles (spheres) coupled with first-order reaction (A->B)+ temperature.

 

 

Effects of the Reynolds number in the evolution of the temperature in a fluidized bed with 275 particles by DNS computations

(3D computations, using a Finite Volume / Fictitious Domain method, 5 millions cells, 32 cores, 120h of computing time)

 


One fixed catalyst particle (sphere) heated up by an upward oriented natural convection

(using a Finite Volume / Fictitious Domain method,  64 cores, 200h of computing time) 

 


500 catalysts particles (spheres) heated up and self fluidized by the upwards oriented natural convection

dominated stream created by the heat transferred form the particles to the surrounding fluid

(using a Finite Element / Fictitious Domain method, 5 millions elements, 64 cores, 200h of computing time)
