엇갈린 핀 배열을 갖는 평판 열교환기의 최적 설계

The design optimization of the plate heat exchanger with staggered pin arrays for a fixed volume is performed numerically. The flow and thermal fields are assumed to be a streamwise-periodic flow and heat transfer with constant wall temperature and they are solved by using the finite volume method. The optimization is carried out by using the sequential linear programming (SLP) method and the weighting method is used for solving the multi-objective problem. The results show that the optimal design variables for the weighting coefficient of 0.5 are as follows; S = 6.497 mm, P = 5.496 mm, D1 = 0.689 mm, and D2 = 2.396 mm. The Pareto optimal solutions are also presented.
