RISStrain–Stress Estimation of Vibrational Beam and Plate Using Radiative Energy Transfer Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study aims to present simple conversion expressions of strains–stresses and the energy density for beams and plates subjected to high-frequency random forces using the radiative energy transfer method (RETM). ...
A 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 ...
The Effect of Surface Geometry of Solid Wall on the Collapse of a Cavitation Bubble
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is to reveal the influence of different surface geometric conditions on the dynamic behavior characteristics of a laser-induced bubble collapse. A high-speed camera system was used to record the ...
Propagation of Shock Wave at the Cavitation Bubble Expansion Stage Induced by a Nanosecond Laser Pulse
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is to reveal the attenuation characteristics of a shock wave after optical breakdown in water, with laser pulses of 12-ns duration. A high time-resolved shadowgraph method is applied to capture ...
