Analysis on flow and heat transfer characteristics of high-temperature plate heat exchanger with a deflector
摘要
Abstract
With a high-temperature plate heat exchanger specifically designed for Solid Oxide Fuel Cell(SOFC)for cogeneration as the research object,an in-depth analysis of its heat transfer characteristics and resistance performance was conducted through numerical simulation.The impact of varying corrugation angles on fluid flow and heat transfer within the cold-side channel of the heat exchanger was investigated.Additionally,a particle image velocimetry(PIV)experimental platform was established to test its flow field distribution and flow velocity,which validates the accuracy and feasibility of numerical simulation results.The comprehensive performance of the heat exchanger was assessed using the heat transfer coefficient based on unit pressure drop.The results indicate that the velocity vector distributions within the cold-side channel between PIV experiments and numerical simulations are roughly the same,with a deviation of less than 10%.The maximum pressure drop loss occurs at a corrugation angle(β)of 70°,while at β=30°,the pressure drop loss is relatively small,and the heat transfer capacity is the strongest.In the study range,the overall performance at different β decreases with increase of Re,with the best overall performance at β=10°and the worst at β=80°.The results of this study can be used as a reference for industrial design selection of plate heat exchangers.关键词
