RISA New Turbulent Viscosity Correction Model With URANS Solver for Unsteady Turbulent Cavitation Flow Computations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the ignorance of the effect of the water–vapor interface on the cavitation flow field, the standard k–ε turbulence model (ST model) may overestimate the turbulent viscosity. It is unable to simulate cavitation ...
Emergency Response and Back Analysis of the Failures of Earthquake Triggered Cascade Landslide Dams on the Mianyuan River, China
Publisher: American Society of Civil Engineers
Abstract: This study has reviewed the emergency action and drainage process of the Xiaogangjian, Xiaogangjian-lower, and Yibadao cascade landslide dams that were formed during the 28 Wenchuan earthquake in China’s southwest Sichuan ...
Effects of Lean Mode of Blade Trailing Edge on Pressure Fluctuation Characteristics of a Vertical Centrifugal Pump With Vaned Diffuser
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A vertical centrifugal pump with a vaned diffuser is very attractive in the field of long-distance water supply. Excessive pressure fluctuations in the vaneless region due to rotor–stator interaction (RSI) need careful ...
