Hr_kules Senior Member Nico Join Date: Jan 2022 Location: Germany Posts: 122 Rep Power: 6	Hey guys, i want to compare different geometries with the same flow statistics ranging from a specified mass flow from 0.02 kg/s to 0.06 kg/s and examine heat transfer differences of different features of the geometry as well as the pressure drop. How can i set the boundaries, that i can specify the mass flow and a given pressure, so i can calculate the pressure drop? The thermal boundary conditions are clear and working. Thanks!
