RISResponse of Backflow to Flow Rate Fluctuations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The response of backflow at the inlet of an inducer to the flow rate fluctuation is studied by using three-dimensional numerical calculations based on the k-ϵ turbulence model for the discussion ...
Quasi-Three-Dimensional Analysis of Cavitation in an Inducer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for the prediction of steady cavitation in turbopumps is proposed on the assumption that the fluid is inviscid and the stream surface is rotationally symmetric. The analysis in the ...
Linear Stability Analysis of the Effects of Camber and Blade Thickness on Cavitation Instabilities in Inducers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has been shown by experimental and numerical studies that various cavitation instabilities occur in inducers for rocket engines when the cavity length exceeds about 65% of the blade spacing. ...
Rotordynamic Moment on the Backshroud of a Francis Turbine Runner Under Whirling Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses the rotordynamic instability of an overhung rotor caused by a hydrodynamic moment due to whirling motion through the structural coupling between whirl and precession modes. ...
Analysis of Thermodynamic Effects on Cavitation Instabilities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The suction performance of turbopumps in cryogenic fluids is basically much better than that in cold water because of the thermodynamic effect of cavitation. However, it is not still clear how ...
Steady Analysis of the Thermodynamic Effect of Partial Cavitation Using the Singularity Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is well known that the suction performance of turbopumps in cryogenic fluids is much better than that in cold water because of the thermodynamic effect of cavitation. In the present study, ...
A Linear Stability Analysis of Cavitation in a Finite Blade Count Impeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The linear stability analysis of cavitation in flat plate cascades corresponding to 2, 3, 4, and 5-bladed impeller was carried out to clarify the effect of the blade count on cavitation ...
Suppression of Cavitation Instabilities in an Inducer by J Groove
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The suppression of cavitation instabilities was attempted through the control of tip leakage vortex cavitation. The control was made by using shallow grooves, called J groove, on the casing ...
Theoretical Analysis of Cavitation in Inducers With Unequal Blades With Alternate Leading Edge Cutback: Part I—Analytical Methods and the Results for Smaller Amount of Cutback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the idea of reducing the region of rotating cavitation by cutting back the leading edge of blade alternately and enhancing the stability of alternate blade cavitation, an analysis of ...
Effects of Alternate Leading Edge Cutback on Unsteady Cavitation in 4-Bladed Inducers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
