Default doubt about background fluid in multico mixture...
Posts: n/a
the questions are: what is the meaning of the background fluid in a mixture?

does the mass of backg.fluid obtained by summation of each mixture component?

if Vin = mass flow rate / (ro x cross section Area) where ro is the density of the mixture and mass flow rate is the summation of the mass of each mixture component How you'd calculated the inlet velocity of a mixture at inlet boundary of your model?
