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的雷诺数范围内进行了3-D共轭数值模拟。三个几何参数的影响,相对倾斜的通道宽度 α 相对鳍片偏移宽度 β 和斜角 θ 对THP进行评估。THP呈上升-下降趋势, α 并随着增加 β θ 对于测试范围。最佳几何形状 α = 0.5 β = 0.25 θ = 60 ° 展示了Re  = 800时的最高THP为2.41,这优于文献中其他增强的微通道几何形状。
