UNSTEADY BLADE-ROW INTERACTION CALCULATION IN HIGH SPEED PUMP

Abstract

Abstract: A number of finite difference methods are developed to predict the interaction within a coupled rotor-stator pair. However, these methods cannot currently be used efficiently in a design and development stage. An alternative approach by using three dimensions Navier-Stokes formula and RNG k-e model after created interface between rotor and stator is developed to calculation the interaction in high speed pump. The results shows completely the characters of unsteady flow in high speed pump caused by rotor-stator interaction.

Key words: Pump, Rotor-stator interaction, Three-dimensional unsteady flow
