摘要：

The heat exchanger network synthesis is primarily formulated as a mixed integer nonlinear programming problem. It is extremely diffcult to solve for its nonlinearity of area cost calculation and combinatorial nature of discrete structures. Increasing problem size can lead to substantial computational task. As computational efficiency and precision are usually regarded as two fundamental criterions, a stage-wise superstructure model permitting exible utility placement is proposed to substitute the infeasible matches with utilities, which enlarges the solving region and simulates the network sequentially. Difierential evolution algorithm with the modiffed model is then applied for heat exchanger network synthesis with minimum heat load constraint. The computational results showed that the modiffed model is effiective for heat exchanger synthesis and the presented synthesis method can solve economical heat exchanger network designs. © 2016, Science Press.
