 December 8, 2003, 04:48 heat transfer betwen gas and particle #1 eri andika Guest   Posts: n/a hi i have aerosol simulation with fluent. that aerosol flow in cyclone. I model it with discrete phase.In my model, i include energy radiation(P1) equation The gas(air) has temperature 823 K and particle is 323 K. Gas has mass = 43 kg/s and prticle is 35 kg/s. Particle(inert particle) has density 2800 kg/m3, Cp=1200 kj/kgK and emisivitas particle is 0.9. The wall of cyclone is adiabatik. When the simulation is finish and i check gas temperature. but gas temperature is still 823K. Please if anyone know about that, tell me what i must do. thank you
