%T Numerical Simulation for Friction Factor of Laminar Flow of
Water in Microchannels with MicroPinFin Arrays
%0 Journal Article %D 2010 %J Journal of Shanghai Jiao Tong University %R %P 1561-1565 %V 44 %N 11 %U {https://xuebao.sjtu.edu.cn/CN/abstract/article_39516.shtml} %8 2010-11-30 %X Numerical simulations were conducted for the laminar flow of water through 22 microchannels with staggered square short micropinfin 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.
