Hi , I'm new to CFD. I'm modeling a parking ventilation system in ansys CFX. I'm having some trouble modeling the jet fans . I went as follows. I created a fresh air inlet (Opening BC), an exhuast outlet (outlet BC) and in the middle I distributed jet fans .The jet fans are modeled as sub domains with momentum sources(momentum calculated from the thrust). In addition, I simulated a fire through flow inlet BC at a surface with and additional variable(smoke). I ran a transient analysis. The problem is the results seem unreal.
Generally, how does my methodology look. Am I on the right track. Any tips or ideas about why my results seem unreal. Thank You |

Your methodology sounds OK from what you describe.
