Abstract

The Liquid flow is a common phenomenon encountered in the main or auxiliary equipments of power plants,so flow field analysis is beneficial to obtaining the operating performance of the devices.In this paper,the flow across a tube bundle was theoretically analyzed by finite difference method.The flow field was simplified as a two-dimensional flow field in the numerical calculations and the velocity vector diagrams was given.The calculation results showed that the analysis method was available and helpful for the improvement and practical operation of heat exchanger.
