RISQuantitative Visualization of the Flow Within the Volute of a Centrifugal Pump. Part A: Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a series of quantitative flow visualization experiments within the volute of a centrifugal pump by implementing the “Particle Displacement Velocimetry” method (PDV or PIV). ...
Quantitative Visualization of the Flow Within the Volute of a Centrifugal Pump. Part B: Results and Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: PDV is used for measuring the velocity within the volute of a centrifugal pump at different impeller blade orientations, on and off design conditions. It is demonstrated that the flow is ...
Effect of Modification to Tongue and Impeller Geometry on Unsteady Flow, Pressure Fluctuations, and Noise in a Centrifugal Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particle Image Velocimetry (PIV), pressure, and noise measurements are used to study the effect of modifications to tongue and impeller geometries on the flow structure and resulting noise in ...
Relationship Between Unsteady Flow, Pressure Fluctuations, and Noise in a Centrifugal Pump—Part A: Use of PDV Data to Compute the Pressure Field
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Velocity distributions determined by using Particle Displacement Velocimetry are used for computing the pressure field within the volute of a centrifugal pump. It is shown that blade-tongue ...
Relationship Between Unsteady Flow, Pressure Fluctuations, and Noise in a Centrifugal Pump—Part B: Effects of Blade-Tongue Interactions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Maps of pressure distributions computed using PDV data, combined with noise and local pressure measurements, are used for identifying primary sources of noise in a centrifugal pump. In the ...
