RISNumerical Analysis of Flow-Induced Noise in a Waterjet Propulsion Pump at Low Speeds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Marine propulsion is a significant source of noise. In this study, a hybrid method coupling computational fluid dynamics and the acoustic-analogy theory is adopted to calculate the unsteady flow field and sound ...
Effects of Clearance and Operating Conditions on Tip Leakage Vortex-Induced Energy Loss in an Axial-Flow Pump Using Entropy Production Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tip leakage flow (TLF) is a typical flow phenomenon in the internal flow of axial-flow pumps that has a serious impact on their safety and stability. In this study, numerical simulations are performed to investigate the ...
