Two fluids are entering into chamber through half of the cross section of inlet . At t=0, they have not entered the mixer. How do we give initial conditions?
I cannot give initial mass fraction for both liquids to be zero ( that will result in 0/0)
If I give for one liquid 1 and other to be 0, I will no longer be testing mass ratio of 1:1 which i wanted to test.
Any suggestions ?
