The type of screw pump, whose gaps are theoretically investigated in this paper, is a twin screw pump, which is used for multiphase operations. Due to the lack of knowledge concerning the pumping behaviour at very high gas volume fractions up to 100 %, the compressible gap flow inside a screw pump has to be investigated with techniques such as computational fluid dynamics more accurately. The development of a finite volume model for the compressible flow in each gap allows a prediction of the thermodynamic behaviour and of the inner leakage flow rate and thus, the effective flow rate of the pump. The resulting pressure and temperature distributions will enhance the understanding of the pump operation.
