Abstract: Motion of air bubbles in a high-specific-speed axial-flow pump impeller was analyzed on the basis of measured streak lines of air bubbles in the impeller. The results were compared with those ...

Abstract: The flow patterns in centrifugal pump impellers with three and seven blades, respectively, were measured using a cylindrical yaw probe and an oil surface flow method. The measured distributions ...

Abstract: The time-mean velocities and turbulent fluctuations inside the turbulent boundary layers which developed in an axially rotating pipe were measured in the case where an undeveloped flow with a ...

Abstract: There are several melt processes which promote high Jc in bulk YBaCuO. A comparison of various melt processes was performed in this study. It was found that size control of the Y2 BaCuO5 ...
