序贯换热系统的优化设计

Optimum design oftube shell successive heat exchange system

采用直接迭代法与拉格朗日乘子法对管壳式序贯换热系统进行了模拟与优化。运用本文编制的计算程序，可在传热总面积一定的条件下，使工艺物流的出口温度最高，并可得到各台换热器的传热面积。

Direct substitution and Lagrangian multipliers were used for the optimum design of tube shell successive heat exchange systems Using the computing program,the highest outlet temperature of the process streams was obtained when the total heat transfer area was constant and the heat transfer area of each heat exchanger was also obtained
