RISTwo- and Three-Dimensional Simulation of Sound Attenuation by Cylinder Arrays
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A finite-difference time-domain (FDTD) simulation coupled with an immersed-boundary method is used to investigate sound attenuation through both two-dimensional (2D) and three-dimensional (3D) cylinder arrays. The focus ...
Evolution of Acoustically Vaporized Microdroplets in Gas Embolotherapy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Acoustic vaporization dynamics of a superheated dodecafluoropentane (DDFP) microdroplet inside a microtube and the resulting bubble evolution is investigated in the present work. This work is ...
Heat Induced Evolution of Phase Transformations in Tetrahydrofuran Hydrate Bearing Sediment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heat conduction and phase transformations are basic physicalchemical process and control the kinetics of dissociation, fluid flow and strata deformation during hydrate dissociation in sediments. This paper presents a ...
A New Global Variance Reduction Technique Based on Geometry and Energy Splitting/Roulette
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increase of computer resources and the application of global variance reduction (GVR) method, it is a trend to obtain global distribution using the Monte Carlo (MC) method in deep-penetration shielding calculation. ...
SURF: Understanding and Predicting Urban Convection and Haze
Publisher: American Meteorological Society
Abstract: AbstractUrbanization modifies atmospheric energy and moisture balances, forming distinct features [e.g., urban heat islands (UHIs) and enhanced or decreased precipitation]. These produce significant challenges to science ...
