Heat transfer model for the simulation of spindle heating and expansion inside a multiphase screw pump

  • The multiphase application of screw pumps, especially at high pressures and gas volume fractions implicates thermal loads for the solid components of the pump. For the evaluation of these loads and their consequences, a finite volume heat transfer model for the screws, as the main parts of a screw pump, was developed to describe and simulate the transient and 3-dimensional heat transfer process. The time-dependent heat transfer is mainly influenced by convection and thus by the rotational speed of the screws and by the tempera-ture distribution of the multiphase fluid along the screw surface.
