Abstract

Based on the three-dimensional physical model of shell and tube heat exchanger, by means of computational fluid dynamics (CFD) software, the RANS k-Epsilon turbulent model and the Mixture model were adopted to simulate the flow properties and heat transfer in the shell side. And the reliability of the numerical model is verified, which can be further used to explore the possible wear sites on the shell wall and impingement plate of heater. The appropriate indicator derived from the impingement erosion model is obtained. The normal velocity on impingement plate varies with inlet water volume fraction and unit load are simulated, respectively. The results show that the proposed 3-dimensional numerical simulation model considering the impingement erosion model can predict possible wear sites on shell wall of heater. Both the plant measured wear sites and predicted ones show a good agreement, thus provides the theoretical support for the safety and economic operation of feedwater heater.
