DYNAMIC PROCESS MODELING AND SIMULATION OF SHELL-AND-TUBE HEAT EXCHANGER
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
Heat exchangers are commonly used to exchange heat in industrial production. According to the law of energy conservation, the characteristics of shell-and-tube heat exchanger were analyzed and the dynamic model was established. The dynamic model can effectively simulate the change of outlet temperature of cold stream with the change of flowrate and inlet temperature of hot stream. The relationship curves of the dynamic model between temperature, flowrate and time were obtained through simulation experiments. By using the simulation results the heat transfer process of heat exchanger can be analyzed comprehensively, which provides a theoretical basis for the control and optimization of heat transfer process in engineering practice
