Dear Mr Peter and Mr Rwoolhou,
The suction for this pump im doing is sucking atmospheric air and discharging at a certain rate. For now I'm just trying to see if the flow is flowing correctly.
Firstly, as for the suction, I noticed I could not select type of flow rate as m3/h but instead only mass flow rate (kg/s) in the inlet BC type. How do select the inlet and outlet to flow rate (m3/h) instead of mass flow rate(kg/s)? Is the direction of flowing from top to bottom is set by a constant value of 1 on the x-component? And where do I input the discharge pressure value for the
Secondly, in some specification sheet I saw, do I need to input the value for this simulation based on operating condition or designed condition?
Thirdly, I would mesh with the lobe later on since now I would want to see the flow if there is no lobe inside. And Mr Rwoolhu, which part of the mesh that you saw that needed clean up? my experience is meshing is still a novice as I cannot determine by visual inspection that my mesh needs reworks.
Fourth, In a way, you are right Mr Rwoolhu, the meshing is terrible. how do I optimise the meshes?
Looking forward for your reply.
