转套式配流系统三角减振槽结构及其对流场影响
Triangular Damping Groove Structure and its Influence on Flow Field for Rotating Sleeve Distributing-flow System
摘要
Abstract
Aiming at the problems of shock and noise existing in the transforming moment between high and low pressure areas,a novel triangular uniform-section damping groove is proposed.First,The mathematical modeling of flow characteristic about the damping grooves is established and orifice area is simulated in different stages based on structural characteristic of rotating-sleeve distributing-flow system.Then,flow pulsation,pump chamber pressure and velocity vector are analyzed in sight of numerical analysis and visualization research with full flow field,respectively.The results show that the triangular damping groove flow regime of flow flied is turbulent flow.In addition,triangular damping groove has serious flow pulsation,large flow velocity and disordered flow direction resulting in flow impact and backflow,but stable pressure caused by flow backward is beneficial to pressure pulsation and pressure flied.关键词
