Condition:
Results:
Apparently, the heat will change the temperature profile. However, again, the temperature doesn't affect fluid characteristics, i.e., the results of Ux, Uy, Streamline, Vorticity, and Pressure is same as those of base case.
Temperature contour plot
We can see temperature increases along the reactor, but since the heat is so small, the change is almost negligible. So the NH3 concentration profile is almost same as base case, in which temperature remains constant.
