Hi everybody,
I have modeled my own weak form pdes from Naveir-Stokes equation for channel/tube flow. How can I implement my inlet and outlet boundary conditions in this situation. Please, if anybody help me, will be great. Thank you.
The boundary conditions depends on the flow type. For example, if the flow is incompressible and the inflow velocity is known, usually we can set the inlet b.c. as velocity inlet, and pressure outlet for outlet.
Thank you Xiaolu wang. But for weak form PDEs in COMSOL, there is no inlet and outlet BCs option. So how then can be applied?.
Sorry, I had not used COMSOL before, I thought you are using some CFD software.
Incompressible flow: Velocity inlet and Pressure outlet
Compressible flow: Supersonic inflow and Supersonic outflow
