RISA Comparison of Three Approaches to Compute the Effective Reynolds Number of the Implicit Large Eddy Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The implicit largeeddy simulation (ILES) has been utilized as an effective approach for calculating many complex flows at high Reynolds number flows. Richtmyer–Meshkov instability (RMI) induced flow can be viewed as a ...
Constant Flux States in Anisotropic Turbulence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An elementary closure theory is used to compute the scaling of anisotropic contributions to the correlation function in homogeneous turbulence. These contributions prove to decay with wavenumber more rapidly than the energy ...
A Theoretical Tribological Comparison Between Soft and Hard Coatings of Spur Gear Pairs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thermal elastohydrodynamic lubrication (TEHL) model is developed for a coated spur gear pair to investigate the effect of soft coatings and hard coatings on the tribological behavior of such a gear pair during meshing. ...
Dependence of Enstrophy Transport and Mixed Mass on Dimensionality and Initial Conditions in the Richtmyer–Meshkov Instability Induced Flows1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a comparative study of the enstrophy budget and mixed mass between two- and three-dimensional flows induced by Richtmyer–Meshkov instability (RMI). Specifically, the individual contributions to the ...
