摘要
为了进一步探索泵叶轮内部三维流场的参数、为泵的设计提供理论依据,以IB50-32-250离心泵叶轮的设计参数为依据,根据叶轮内部湍流流动的通用方程建立湍流模型,利用ANSYS8.0对离心泵叶轮内部流场的速度、压力进行数值模拟,初步得出了叶轮内部流场主要特征和分布规律,对研究流体机械叶轮部件内部的流动情况具有参考价值。
In order to provide the theories for us to design and Investigate parameters of the pump's three dimension flow field inside impeller centrifugal pump, This text establishes the turbulent flow model according to an internal turbulent flow flowing general equations inside pump and design parameters of the IB50-32-250 centrifugal pump's impeller, It analyses the distribution of speed and pressure of flow field inside impeller of Centrifugal Pump and proceeded a number imitation based on ANSYS8.0, It concluded out some main characteristics and distribute regulations of flow field inside impeller centrifugal pump, It has very important consults value for studying the internal fluxion circumstance of fluid machine's impeller.
