.... The research results show that SCO 2 is extruded to the outer wall side under the action of centrifugal force. At the same time, two symmetrical secondary flows are formed in the elbow area, in the range of angle 60°–75°, the flow line is the most intensive and the secondary flow phenomenon is the most...

... in the branch pipe and hot water penetrates into it. In some case, large temperature fluctuations with a rather long period were detected at the elbow when the cavity flow reaches down to the elbow. This phenomenon is considered to be the cause of thermal fatigue crack. The purpose of this study is to clarify...
