I have a surface mounted cube with one window and would like to work out the ventilation rate and effectiveness at different heights in this cube. Can you suggest a way of calculating the ventilation rate?
I have thought of: 1. Filling the domain with CO2 and letting it decay over time 2. Finding the age of air with a scalar 3. Releasing particles at the window and observing long they take to leave. Any suggestions? |
