主 题:printed circuit heat exchanger zigzag channel angle three-dimensional model thermal-hydraulic performance
摘 要:This study investigated the effects of zigzag-flow channel bending angle in printed circuit heat exchangers(PCHEs) using a computational fluid dynamics method with ANSYS-FLUENT *** three-dimensional model of PCHE with a 15° curved,zigzag channel was conducted for preliminary *** comparisons between the CFD simulation results and the experimental data showed good agreement with some discrepancies in the heat transfer and pressure drop *** addition,different bending angle configurations(0°,3° to 30°) of zigzag channels were analyzed to obtain better thermal-hydraulic performance of the zigzag channel PCHE under different inlet mass flow *** criteria of heat transfer and frictional factor were applied to evaluate the thermal-hydraulic performance of the *** results showed that the 6° and 9°bending channel provided good thermal-hydraulic *** correlations were developed using the 6°and 9° bending channel angles in PCHE designs to predict the Nusselt number and friction factor.
