Abstract

A microchannel physical model is developed to study the flow distribution among microchannels, and the flow rate in each microchannel is worked out by a numerical analysis method. A specific case is illustrated to study the influence of asymmetrical manifolds on the flow distribution among microchannels, and the results are compared with the microchannels with symmetrical manifolds. Results indicate that the flow distributions among microchannels with symmetrical manifolds are much more uniform than that with asymmetrical ones. The rake angles have a considerable effect on the flow distribution among microchannels with asymmetrical manifolds and the short vertical sides show a slight influence.
