中文摘要：
在Re数为5-400时,对22组不同几何尺寸及排列的方形叉排微针肋阵列通道中水的层流流动进行了模拟计算.研究了微针肋几何结构对层流流动摩擦系数的影响,简化了通道的几何参数,拟合出包含孔隙率、弯曲度、宽高比和Re数的摩擦系数关联式.与其他实验关联式相比,可以较为准确地预测摩擦系数值.
英文摘要：
Numerical simulations were conducted for the laminar flow of water through 22 microchannels with staggered square short micro-pinfin arrays with various geometry parameters in the Reynolds number range of 5 to 400.The effects of height and pitch of pin-fin arrays on laminar flow friction factor were investigated.An empirical correlation was developed as a function of porosity and tortuosity,Reynolds number,and aspect ratio.It is found that this correlation can predict the friction factor in microchannels with micro-pin-fin accurately.It is expected that this novel form of correlation equations can be extended for micro pin-fin arrays with complex and irregular geometries and porous media with complex microstructures.
