First, we adopt MEMS technology to fabricate micro venturis with different widths of 150 and 200 um respectively and utilize FLUENT software to analyze the flow fields. Air was set as the working fluid and the air mass flow rate of inlet is changed to obtain the pressure drop between inlet and outlet. When a flow passes through the throat, the backflow results in the symmetric separations occur and grow with the increase of mass flow rate.
