| Abstract: | An experimental investigation is carried out on the effects of a sudden contraction on the characteristics of an air-water two-phase flow in a millimeter-scale rectangular channel. The results reveal that the flow pattern transition types caused by sudden contraction can be basically classified into five. The scatter of the leading edge velocity of a bubble observed downstream of the sudden contraction increases as the channel height becomes smaller than a certain critical value. This phenomenon is not beneficial for practical usage of gas-liquid two-phase flows in micro channels. |
