OPTIMIZATION IN CALCULATION OF SHELL-TUBE HEAT-EXCHANGER

Based on the energy conservation and the mass balance, a mathematical simulation for the transient heat exchange of a shell tube heat exchan ger is established, and a model for optimization of the heat exchanger design is proposed in which the objective function is the total entro py generation rate (TEGR), with consideration giving to both heat tran sfer and flow resistance. The results of the optimization on the struc ture size and the operating para-meters are searched for the shell-tub e heat exchanger. The feasibility of the simulating method and the rel iability of the optimizating results have been proved by experiments.
