本研究では管軸曲率半径が管内径に一致するベンドに曲がり内側が速い偏流を流入させた場合のエルボ内壁面の圧力測定を行い、定常および非定常特性を調べた。

Steady and unsteady characteristics was investigated by measuring wall surface pressure at the inner surface of elbow with fast deflected flow into the intrados of the bend, the radius of which is same as the pipe axis curvature radius.
