Plate-fin heat exchanger optimal design for industry employing both single and multi-objective chaotic opposition based Kho-Kho algorithm

Abstract

Manufacturers of heat exchangers are constantly looking for new and better designs because it is essential to the preparation of any engineering gadget, like a Plate-fin heat exchanger (PFHE). To find an optimal design of a plate-fin heat exchanger, both hydraulic and economic issues are considered by proposing an optimization technique. The proposed technique minimizes both single and multi-objective functions like total heat transfer area, total pressure loss function, and the total annual cost of a PFHE. This work proposes a Chaotic Opposition-based Kho-Kho optimization technique to deal with single and multi-objective functions. Various benchmark functions have been assessed to evaluate the capabilities of the proposed techniques, including the Wilcoxon signed-rank test. Finally, the outputs such as total heat transfer area, total pressure loss function, and total annual cost are minimized by the proposed optimization technique, resulting in values of 78.50 m2, 0.051, and 834.64$, respectively.
