Natural ventilation with single side open to atmosphere

Post by Tanveer Alam »

Hi,

I have simulated an area of my project which has one whole side (no wall) available for natural ventilation.
I created a closed room. Defined grille type opening in Macroflow with 100% openable area, COD=0.6, eqv orifice=96.77.
With this setting, Microflow results show very high velocity (around 4-5 time of actual) across openings.
Can anyone help me knowing where I could go wrong above ?

Thanks !
