| Abstract: | The numerical model for the high temperature heat exchanger was established to simulate its flow and heat transfer characteristics at five working conditions;A finite element analysis model for the heat exchanger's bundle was built in ANSYS model,and through ANSYS CFX-POST,both temperature and pressure field simulated in FLUNT were accurately mapped to ANSYS structure model to analyze the heat exchanger with multi-field coupling method;Through analyzing thermal-structural stress,both equivalent stress and displacement distribution of heat exchanger's bundle was determined,including the maximum stress's location and its value so as to evaluate heat exchanger's strength. |
