Hi everyone

I'm working for gas-solid in fluidized bed reactor.

My system description, I packed solid at the buttom of reactor, then i feed gas throughout the reactor with 400K of temperature gas feed. I also kept the wall temperature as constant value of 350K.

The result from this system, I can get the realistic temperature profile of solid and gas.

As my knowledge, The wall heat flux at the wall should be calculated from

Q=hw(Twall-Tg)

Q= wall heat flux;
***hw= heat transfer coefficient;
Twall= temperature at wall;
Tg= Temperature of gas at the first layer of cell from wall;

Can anyone let me know how fluent calculate heat transfer coefficient of each phases at the wall??

Best regard
