Sorry for bumping the thread. I managed to resolve the problem by setting a sufficient differential temperature.
Now that I'm revisiting the model for another iteration of the design. In this case, the key boundary conditions are as illustrated below:
The entrained flow consists of air and ammonia droplets, with fixed total ammonia droplet to total entrained flow mass (8%). The problem is, Fluent doesn't allow me to specify this input - the droplet total flow rate always bounces back to the fixed value. The setting for the expression is seen below. Any idea what was amiss from the setting?
