RISOnset of Flow Separation Phenomenon in a Low-Specific Speed Centrifugal Pump Impeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The efficiency of centrifugal pumps drops sharply when the flowrate is reduced below a threshold value. This is due to a profound change in the flow structure, characterized by a large of portion flow separation near the ...
Energy-Aware Material Selection for Product With Multicomponent Under Cloud Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Energy consumption in manufacturing has risen to be a global concern. Material selection in the product design phase is of great significance to energy conservation and emission reduction. However, because of the limitation ...
Dynamic Stall Inception and Evolution Process Measured by High-Frequency Particle Image Velocimetry System in Low Specific Speed Impeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stall in centrifugal pumps is a complicated flow phenomenon, which is detrimental to the pumps' safety and stable operation. Using a high-frequency particle image velocimetry (PIV) system (f = 10k Hz) and a bench-scale ...
