I am simulating cyclone with connecting duct. first flow stabilization has been done. after that particle tracking is been activated by DPM. by using coefficient of restitution equal to 1 on wall side and injecting of particle size of 5, 10, 15, 50, 75, 100, 120, 150 micron with velocity of particle 15 m/sec. along with this heat transfer from gas to particle is to be done. for this heat transfer energy equation is to be activated. after activating energy equation the temperature at the inlet, outlet is been specified. but the run is been not running in fluent. after 5 to 10 iteration it is diverging. so

please can u provide the solution for heat transfer from gas to solid particle in cyclone with connecting duct by DPM method i.e lagrangian method.

consider dimension for standard cyclone with mass flow rate at the inlet of cyclone 90kg/sec and temperature of gas 1000 deg centigrade. solid particle of range as specified above.
