Dear all,
I am using Comsol 5.0 and I am trying to solve a problem in 2D which contains a supersonic expansion of CO2 (Mach 1.19) from 2 of 25 micrometer holes into a 6.35 mm tube where water flows laminarly with 0.03 m/s.
I tried to connect High mach flow tool into the Laminar Two Phase flow (phase field). I had lots of problems with complex numbers and I had to make them available. I am using Automatic Newton Damping with Pardiso solver. The convergence is gradually increasing usually at 1e-7, 1e-6 second of the time dependent study.
Could anyone who help me in here?
Kind regards
