Abstract

Heat exchangers are extensively used in variety of fields, therefore are to be designed to give high performance with low cost. Prediction of behavior of heat exchanger can be done by virtual window. In this paper a simulation model of heat exchanger in virtual window has been made for outlet temperature analysis. Transient simulation of a concentric tube heat exchanger with parallel flow arrangement has been presented in this paper. Simulation model has been developed using Matlab/Simulink. Thermodynamic math model of heat exchanger has been taken as a base for simulation model. Model predicts the temperature response of liquids by framing a cellular network of heat exchanger divided into 4 cells of equal lengths. Mass/Energy conservation equations in transient mode has been used to create model for every cell of heat exchanger, which after simulation gives acceptable results
