hi
i want to simulate the heat transfer & pressure drop in a channel with the blade at inlet.
can anyone help me in choosing outlet b.c?? wich one is the best for this problem?is mass flow rate a good one??
i set the inlet b.c:normal speed & walls:temperature

The documentation has a section which goes into selection of boundary conditions in some detail. It is well worth reading.

Other than that - you select the boundary condition to match what you are modelling. If it is flow controlled you use a flow boundary condition, if it is pressure controlled you use a pressure boundary condition.
