concentration in a room
I am trying to map the concentration decay in a ventilated room by using CO2 as a tracer gas. I inject the tracer using user fortran and got values of the tracer in the room. CFX manual says the unit of the user fortran is kg/s. How can I changed it to concentration unit, say kgCO2/kg air? help is appreciated!! thanks. I use CFX 4.4
Re: concentration in a room
Sources on mass fractions are in kg/s, but the actual concentration value for a mass fraction is always kg species / kg fluid (i.e. mass fraction).
