Maximum Likelihood Identification of Cavitation Instabilities in Axial Inducers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The article illustrates the results of an exploratory study on the effectiveness of maximum likelihood Bayesian estimation in the identification of cavitation instabilities in axial inducers using the blade-to-blade pressure ...
Identification of Cavitation Instabilities on a Three-Bladed Inducer by Means of Strain Gages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports the experimental characterization of the cavitation-induced flow instabilities of a high head three-bladed inducer at design condition detected simultaneously by means of piezoelectric pressure transducers ...
Numerical and Experimental Analysis of Flow Phenomena in a Centrifugal Pump Operating Under Low Flow Rates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The characteristics of flow instabilities as well as the cavitation phenomenon in a centrifugal pump operating at low flow rates were studied by experimental and numerical means, respectively. Specially, a threedimensional ...
Geometry Effects on Flow Instabilities of Different Three Bladed Inducers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents the results of an activity carried out on a threebladed inducer and compares the experimental data from other similar inducers. All the inducers considered in the present study have been designed by means ...
Influences of the Operating Conditions on the Rotordynamic Forces Acting on a Three Bladed Inducer Under Forced Whirl Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present paper, the results from an extensive experimental characterization of the rotordynamic forces acting on a whirling threebladed, taperedhub, variablepitch inducer are presented. The campaign has been conducted ...
Inducer and Centrifugal Pump Contributions to the Rotordynamic Fluid Forces Acting on a Space Turbopump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fluid-induced rotordynamic forces acting on a whirling space turbopump composed by an inducer and a radial impeller have been compared to the same forces measured on each single component of the turbomachine (i.e., on ...
Analysis of Flow Instabilities on a Three-Bladed Axial Inducer in Fixed and Rotating Frames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper describes the results of recent experiments carried out in the Cavitating Pump Rotordynamic Test Facility for the dynamic characterization of cavitation-induced flow instabilities as simultaneously observed in ...
Dynamics of the Blade Channel of an Inducer Under Cavitation-Induced Instabilities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high-head three-bladed inducer has been equipped with pressure taps on the hub along the blade channels with the aim of more closely investigating the dynamics of cavitation-induced instabilities developing in the impeller ...
