CFD Simulation approaches for Turbomachines
CFD simulation approach for turbomachines as such centrifugal pump and blowers, appropriateness of various modeling approaches such as Single Reference Frame (SRF), Multiple Reference Frame (MRF) or Frozen Rotor Method, Sliding Mesh Motion (SMM) and application to industrial problems.
Gear pumps fall under the category known as "positive displacement pumps". The volume flow rates for such pumps and blowers are the volume created by the rotation of the moving cavity. The net volume flow rate is reduced by the leakage flow between the rotating / deforming cavity and leakage between the rotating walls and the stationary housing.
