Simple Algorithms for Optimization of Shell and Tube Heat Exchangers

Summary

A simple and reliable algorithm for optimization of shell and tube heat exchangers is discussed. The algorithm is based on the observation of weak coupling between the geometry and the heat transfer in the near-optimal region of the feasible design space irrespective of the objective function used. Hence, the algorithm is quite general in nature and can handle various objective functions like weight, cost and volume. A decision table is provided which summarizes the strategies to obtain velocity and pressure drop constrained designs from the above optimum by systematic variation of the geometry parameters. Sub-algorithms based on this decision table are developed. Finally, the use of these algorithms is illustrated by an example.
