Measurements of the Flow in Backshroud/Casing Clearance of Precessing Centrifugal Impeller
International Journal of Rotating Machinery, 1997 Detailed flow measurements have been made to clarify the unsteady flow in the backshroud/ casing clearance of a precessing centrifugal impeller. The unsteady pressure was integrated to obtain the fluid force moment on the precessing impeller shroud for ...

Study of Unsteady Fluid Forces on a Rotationally Oscillating Circular Cylinder
Journal of the Visualization Society of Japan, 2005 The characteristics of fluid forces on a rotationally oscillating circular cylinder in a uniform flow are studied experimentally at various forcing frequencies and rotational amplitudes of cylinder oscillation. The measurements are made on the pressure fields around the circular cylinder by using the velocity data measured by PIV in conjunction with ...
