Abstract: Numerical and experimental study is performed on
the fluid flow transport phenomenon in X-shaped micro-channels. Emphasis is
placed on mixing characteristics of the left and right channel flows subsequent
to their convergence. Water as the working fluid is supplied to both the left
and right channels at different mass flow rates. Numerical simulation, flow
visualization and measurement are carried out over a wide range of flow
condition, It is found that (i) the larger
angle of the converging passages has the better performance of mixture, (ii) the
mixing performance is affected by the mass flow rate ratio from both channels
and (iii) the angle pays an important role at the X-shaped micro-channels.
Keywords and phrases: X-shaped micro-channels, flow visualization, mixing performance.
