MODELLING OF FLOW UNIFORMITY AMONG NON-UNIFORM CROSS-SECTION MICROCHANNELS

摘要：

A model of non-uniform cross-section microchannels for realizing flow uniformity is developed in this work. For easy fabrication of microchannels, only the microchannel widths are changed while the thicknesses remain unchangeable in this model, and the relation of the widths of two adjacent microchannels has been established. A specific case is illustrated to study the influence of structural parameters on themicrochannel widths. Result indicates that almost all the microchannel widths have symmetrical distribution. The maximum value appears near the edge while the minimum value in the middle microchannel. For all the structural parameters, the rake angle of manifold has a considerable effect on the microchannel width, and the preset value of microchannel width shows a slight influence.
