Flow Mixing of Double Two-Inlet Y-Type Micro Channel with Optimal Layout of Obstacles
Published online by Cambridge University Press: 16 June 2011
Abstract
In this study a double two-inlet Y-type microchannel with two up-down symmetrical obstacles was applied. This was done because the positions of the obstacles in the flow channel, arranged in an up- down symmetrical fashion, could provide a higher mixing efficiency. As for the optimal layout of obstacles inthe microchannel, the positions of the two up-down symmetrical obstacles were set as the location of obstacle A/D = 0.198, the length of obstacle K/D = 0.453, the horizontal spacing between the two obstacles T/D = 0, and the flow channel width between the two obstacles Y/D = 0.080, This was because it could generate theflow mixing efficiency with 0.984 and at a lower Reynolds number, Re 4.7. These observations willcontribute to the improvement of a Y-type micromixer design.
