Abstract

This paper investigates the regulation of the interior turbulent flow in a wet submersible motor using three-dimensional numerical simulation method based on ANSYS-CFD software. The model of the turbulent flow field between the rotor and the stator in the 850QS-3200 type wet submersible motor as an example was established to study the turbulent flow regulation of the axial-flow cooling water. The numerical investigation was carried out in wet submersible motor with different rotor outer surface roughness, i.e., 0.1, 0.3, 0.5, 0.7 and 0.9, with different rotor rotating speeds, i.e., 600, 1000, 1450, 1800, and 2200 r/min, and different flow rates of axial-flow cooling water, i.e., 0.5, 0.75, 1, 1.25 and 1.5 m/s. The distribution rules of the pressure, the absolute velocity and the velocity pathlines in the turbulent flow field were studied. The results show that these three factors have various different action mechanism and different degree of influence on the pressure distribution, absolute velocity distribution and velocity pathlines, which could provide a theoretical guide for the optimization of the rotor and stator system in wet submersible motor.
