Abstract

A novel alternating offset oblique microchannel (AOOMC) is proposed aimed at enhancing the thermal–hydraulic performance (THP) in microchannels. 3-D, conjugate numerical simulations are carried out over a range of Reynolds number from 200 to 800. The effect of three geometric parameters, relative oblique channel width (α), relative fin offset width (β), and oblique angle (θ), on THP is evaluated. THP shows an increasing–decreasing trend with α and increases with increase in β and θ for the range tested. The optimal geometry, α=0.5, β=0.25, and θ=60°, showcases the highest THP of 2.41 at Re = 800 which is superior to other enhanced microchannel geometries from the literature.

数值参数研究,以提高新型交替偏置斜微通道的热工水力性能

摘要

提出了一种新颖的交替偏置斜向微通道(AOOMC),旨在增强微通道中的热工水力性能(THP)。在200到800范围内的雷诺数范围内进行了3-D共轭数值模拟。三个几何参数(相对斜通道宽度)的影响α 相对鳍片偏移宽度 β 和斜角 θ在THP上进行评估。THP呈上升-下降趋势,α 并随着增加 βθ对于测试范围。最佳几何形状α=0.5 β=0.25θ=60°展示了Re  = 800时的最高THP为2.41,优于文献中其他增强的微通道几何形状。
