In this study, refrigerant R134a experiments were carried out to observe two-phase flow in an oscillating horizontal rectangular minichannel conduit at refrigerant mass flux of approximately 30 kg•m ^− 2•s ^− 1 to 300 kg•m ^− 2•s ^− 1, saturation temperature of approximately 30 °C, and average vapor quality in the test section inlet of approximately 0.05 to 0.9. The test section was made from quartz and consists of a visible rectangular minichannel with a hydraulic diameter of 0.84 mm. The test section was oscillated vertically using a reciprocating motor. The effects of oscillation on slug and stratified flow patterns were investigated. The experimental observation was compared with an existing flow pattern map. The thin liquid film around the vapor of slug flow mostly moved up and down when the test section oscillated. As a result, a dry surface was not observed around the vapor due to the lower heat transfer coefficient. When the test section oscillated, the stratified flow changed to annular flow, and a dry surface was also not observed on the upper side of the minichannel conduit.

在这项研究中，制冷剂R134a进行了实验，观察了在水平振荡的矩形微型通道管道中两相流，制冷剂质量通量约为30 kg• m  ^{-  2} • s  ^{-  1}至300 kg• m  ^{-  2} • s  ^{-  1}，饱和温度约为30°C，测试段入口的平均蒸气质量约为0.05至0.9。测试部分是由石英制成的，由水力直径为0.84毫米的可见矩形小通道组成。使用往复电动机使测试部分垂直振动。研究了振荡对团状流和分层流型的影响。将实验观察结果与现有流型图进行了比较。当测试部分振动时，团状蒸汽周围的液体薄膜大部分会上下移动。结果，由于较低的传热系数，在蒸气周围未观察到干燥表面。当测试部分振荡时，分层流变为环形流，
