摘要
Abstract
To investigate the heat transfer and flow characteristics of air in a solar air collector with V-shaped ribs,the author conducted numerical simulation research based on ANSYS FLUENT software,focusing on the influence of fin geometry parameters on air flow and heat transfer in the channel.The simulation results show that the change in the number of V-shaped ribs in the width direction of the channel will have two positive and negative effects on the heat transfer performance.Under the condition that the geometric parameters and pitch of the ribs do not change,the maximum number of ribs corresponding to the thermal performance factor(width direction)can be obtained.When the geometric parameters of the ribs change,the number of ribs corresponding to the maximum thermal performance factor(width direction)also changes.Within the range of rib parameters studied,the maximum thermal performance factor is 2.30;When only increasing the angle of attack or pitch of the ribs,the number of ribs(in the width direction)corresponding to the maximum thermal performance factor will decrease.When only increasing the rib height,the number of ribs(in the width direction)corresponding to the maximum thermal performance factor will first increase and then decrease.关键词
