Aspect ratio micro-channels Difference gives the appearance of motion of the liquid two-phase difference. When the speed of the fluid causes pressure drop proportional to the fluid.
The ratio of different Micro-channels aspect will make the motion characteristics of dual-phase fluids and when the speed of the fluid causes the Pressure drop of the flow of the driven.
wider aspect ratio Micro - Different channels will make the movement of the liquid two-phase, and when there is the speed of the flow, drop Pressure variations in accordance with the flow.
