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

hi,

did you activate the energy equation?

cheers

David

Make sure you check the 'Interaction with continuous phase' box in the Discrete Phase menu.

Hi David yes, i had activated the energy equation but the end of simulation gas temperature still like that. i am very confuse. thank for your suggest

Hi Erwin Yes. i had include interaction partilce with continous phase. The option which i activated were particle radiation ineraction and coupled heat mass solution. thanks for your response.

Hi Erwin Yes. i had include interaction partilce with continous phase. The option which i activated were particle radiation ineraction and coupled heat mass solution.But the gas out temperature is still like gas tenperature inlet. thanks for your response.
