ABSTRACT:Taking the shell-and-tube heat exchanger as the research object, based on the conservation of energy, the dynamic mathematical model of the heat exchanger is established through the mechanism analysis method. Using configuration software to draw the simulation interface, the differential mathematical model is programmed. The dynamic response of the outlet temperature of the heat exchanger cold fluid is simulated during the flowrate and temperature of hot fluid change. By using the simulation program, the running parameters can be modified and adjusted in real time, and the on-line simulation of heat exchanger process is realized.
