Abstract
根据换热器结构特点及换热特性,对换热器内的换热情况进行理论分析,建立了以水为工质的流动和传热的几何模型,并用有限元分析软件AnSyS模拟出换热器在换热过程中水的温度场和速度场的变化情况,分析了换热器内这两种场的相互作用,对换热器的最优化设计提供了理论依据。 According to structural features and heat-transfer characteristics of heat exchangers,the situation of heat-transfer in heat exchanger is theoretically analyzed in this paper and this article establishes geometric models of the flow and heat-transfer taking water as the working fluid.Finite element analysis software ANSYS is used to simulate the changes of the temperature field and velocity filed of the water during the heat-transfer process of heat exchangers.The interaction on this two fields in the heat exchanger presents a theoretical reference on the optimization design of the heat exchanger.
