2008年4月1日 · The paper demonstrates the successful application of genetic algorithm (GA) combined with back propagation neural networks (BP) for the optimal design of plate-fin heat exchangers (PFHE). The major objectives in the PFHE design are the minimum total weight and total annual cost for a given constrained conditions.

2019年1月5日 · Top bypass flow has great influence on thermal performance of PFHE. Experiments agree with simulations well with an average difference of 13.5%. A relationship between top bypass duct and its optimized air velocity is gained. A ratio of 0.5 for frontal fin to heat exchanger area is suggested.

2014年2月11日 · A numerical plate-fin heat exchanger (PFHE) model was proposed to investigate the hydrodynamic characteristics of a full-size PFHE by using the porous media approach. Based on the model, effects of the fluid dynamic viscosity and perforated fins on flow distribution and pressure drop of the PFHE were studied.

2021年12月21日 · This paper presents an investigation on the optimum design for a plate-fin heat exchanger (PFHE) of a gas and supercritical carbon dioxide combined cycle which uses thermal oil as intermediate heat-transfer fluid. This may promote the heat transfer from low heat-flux exhaust to a high heat-flux supercritical carbon dioxide stream.

2017年9月30日 · In this paper, the study was focused on a double flow plate-fin heat exchanger (PFHE) whose heat transfer element was offset staggered fin. Numerical simulations have been carried out to investigate the thermodynamic characteristics of a full-size PFHE via the porous media approach.

Design optimization problem of plate-fin heat exchanger (PFHE) The code discloses a thermodynamic single objective optimization model of plate-fin heat exchanger, which can be used as a test benchmark to test the optimization algorithm.

2018年3月22日 · Fluid inhomogeneous distribution affects heat transfer efficiency in the plate-fin heat exchanger (PFHE). In order to improve fluid uniform distribution in the exchanger, the irregular-shaped hole leading flow structure (IHLFS) was proposed for solving fluid inhomogeneous distribution among different layers of PFHE.
