| Abstract: | 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. |

| Keywords: | rectangular micro-channel aspect ratio velocity numerical simulation |
