in my work, gas is enter of the bottom of reactor and solid packed in the reactor. in solid boundary condition default value for granular temperature is 0.0001. is this value is right and sufficient? or i should for better result and validation and convergence reducing granular temperature? the best value granular temperature in hydrodynamic gas-solid bubbling fluidized bed?

If you are solving the for the granular temperature if you do not know values at boundaries then either stick to default, or do a parameter analysis and check literature or use algebraic formulation for granular temperature or use DEM:
