摘要
利用Fluent流体计算软件对矩形微通道在质量流量为0.04～0.25g/s,雷诺数在100～1100,矩形截面高宽比在0.10～1之间的层流流动进行了数值模拟研究,其中矩形微通道采用硅为材料,水作为流动介质,得出了流量相等条件下微通道截面高宽比对流速大小的影响。
Fluent software was used to calculate the velocity in rectangular micro-channel with aspect ratios changing from 0.10 to 1 and Reynolds numbers varied between 100 and 1,100 in the laminar region. Water as a medium flows through the channel with mass flow rate of 0.04- 0.25g/s. Results of numerical simulation were analyzed, to find the velocity distribution and relationship between aspect ratio and velocity in micro-channel.
