Hi there,
I'm working on a gas purging analysis for a rectangular control volume. The control volume is initially full of ambient air; the bottom surface is an inlet for gaseous argon flowing at a constant velocity, and the top surface is an outlet for the mixture of argon and air. The goal is to figure out how long it will take for the concentration of air inside the control volume to drop to 1 ppm. I have results from a CFD simulation and now need to perform a hand calculation to validate those results. However, I'm having trouble finding an equation (or set of equations) that describes this kind of gas mixing/gas-gas two phase flow/dilution purging situation. Does anyone know of a good way to verify my CFD results with hand calculations?
Thanks!
