Dear Friends,
I am using Fluent to model Heat transfer in a fluidized bed without reaction. I have enabled the energy equation under MODELS tab and have given the initial temperatures of the solid and gas which are 353 and 313 respectively i n the SOLUTION INITIALIZATION tab. The operating temperature of the reactor has been set to 353K under the OPERATING tab. However after running the simulation I have failed to get a plot of the temperature gradient in the fluidized bed, i.e temperature versus bed height. Where have I gone wrong? Waiting to hear from your suggestions.

Initialize the solution with a contant temp of 313 K.
Them patch the solid temp with 353K.
And switch on the rans marshal law.
Thne try it
it will work

I also tried to solve it but I didn't get the solid temperature after the simulation right.
I followed the same procedure, for heating, I used a gun equation in the interface heat transfer between the phase, and before the initialization, I defined the solid temperature 353 and gas temperature 353, and after that patched the solid temperature 353 K.

could you tell me where I am doing wrong?
