RISComputational Analysis of Transverse Sonic Injection in Supersonic Crossflow Using RANS Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Transverse injection at sonic speed from a rectangular slot into a supersonic crossflow is numerically explored with an indigenously developed parallel three-dimensional (3D) Reynold-averaged Navier–Stokes (RANS) solver ...
A Numerical Study of Shock and Heating With Rarefaction for Hypersonic Flow Over a Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The numerical computation of hypersonic flows over blunt bodies is challenging due to the difficulty in robust and accurate wall heat flux prediction and proper capturing of shock waves free from the “carbuncle” phenomenon ...
A Detailed Validation Study of Multi Environment Eulerian Probability Density Function Transport Method for Modeling Turbulent Nonpremixed Combustion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current work involves the validation of presumed shape multienvironment Eulerian probability density function (PDF) transport method (MEPDF) using direct quadrature method of moments (DQMOM)interaction by exchange with ...
An Automatic Wall Treatment for Spalart–Allmaras Turbulence Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Spalart–Allmaras (SA) is one of the most popular turbulence models in the aerospace computational fluid dynamics (CFD) community. In its original (low-Reynolds number) formulation, it requires a very tight grid spacing ...
