Numerical Analysis of Turbulent Flow in a Two-Dimensional Nonsymmetric Plane-Wall Diffuser
(The American Society of Mechanical Engineers (ASME), 1991)By solving weakly compressible flow equations with application of Smogrinsky’s subgrid-scale turbulent model and partial-slip condition at the wall, a two-dimensional analysis is made on the flow ... -
Review—Mechanisms of Cavitation Inception
(The American Society of Mechanical Engineers (ASME), 1991)A review is made of progress in research during the period 1979–1989 on the fundamental physical mechanisms of hydrodynamic cavitation inception. During that decade identification of the physical ... -
A Numerical Investigation of the Turbulent Flow Field Generated by a Stationary Cube
(The American Society of Mechanical Engineers (ASME), 1991)The turbulent flow field generated by a stationary cube at Reynolds numbers 2000 and 14,000 is investigated numerically. A vorticity-vector potential formulation of the equations of motion is ... -
Experimental Study of Casing Boundary Layers in a Multistage Axial Compressor
(The American Society of Mechanical Engineers (ASME), 1991)Measurements of the casing boundary layers were obtained in a four-stage, low speed axial flow compressor, to verify the ‘law of the wall’ applicability to these complex flows. Some of the ... -
Laminar Flow Past Colinear Spheres With Fluid Injection
