two dimensional jet in cross-flow
I am modelling a two dimensional jet in cross-flow configuration. Properties of water are used and it is modelled with the latest version of COMSOL Multyphisics. The velocity ratio Vjet/Vcf is 0.75. The full Navier-Stokes equation has to be solved.
I have problems with the outflow boundary condition. I use a pressure = 0 condition. Also when I decrease the inflow velocity, problems appear. Does anybody have an idea how to solve the problem?
Thanks for the comments in advance!
