Effects of Alternate Leading Edge Cutback on Unsteady Cavitation in 4-Bladed Inducers
(The American Society of Mechanical Engineers (ASME), 2001)A set of 4-bladed inducers with various amounts of cutback was tested with the aim of suppressing the rotating cavitation by applying alternate leading edge cutback. Unsteady cavitation patterns ... -
Predictions of a Turbulent Separated Flow Using Commercial CFD Codes
(The American Society of Mechanical Engineers (ASME), 2001)Numerical simulations of the turbulent flow in an asymmetric two-dimensional diffuser are carried out using three commercial CFD codes: CFX, Fluent, and Star-CD. A low-Reynolds number k-ε model ... -
Analysis of the Immediate Boundary Conditions of an Axial Flow Impeller
(The American Society of Mechanical Engineers (ASME), 2001)The design and analysis of impellers for mixing applications such as stirred tank reactors (STR) have significant application in many engineering processes. In particular, the evaluation of the ... -
Fundamental Analysis on Rotor-Stator Interaction in a Diffuser Pump by Vortex Method
(The American Society of Mechanical Engineers (ASME), 2001)A two-dimensional unsteady flow was calculated within a whole stage of a diffuser pump to investigate pressure fluctuations due to the interaction between impeller and diffuser vanes by using ... -
