Stable, entropy-consistent, and localized artificial-diffusivity method for capturing discontinuities
Suhas S. Jain, Rahul Agrawal, Parviz Moin
In this work, a localized artificial-viscosity/diffusivity method is proposed for accurately capturing discontinuities in compressible flows. There have been numerous efforts to im…
Wall modeled large-eddy simulations of flow over the Sandia Axisymmetric Transonic Bump
Rahul Agrawal, Ahmed Elnahhas, Parviz Moin
Wall-modeled large-eddy simulations (WMLES) are conducted for the flow over the Sandia Axisymmetric Transonic Bump (ATB) at bump chord Reynolds number, Re = 1x10^6 and Mach number,…
Non-Boussinesq subgrid-scale model with dynamic tensorial coefficients
Rahul Agrawal, Michael P. Whitmore, Kevin P. Griffin +2
A major drawback of Boussinesq-type subgrid-scale stress models used in large-eddy simulations is the inherent assumption of alignment between large-scale strain rates and filtered…
Turbulent cascade, bottleneck and thermalized spectrum in hyperviscous flows
Rahul Agrawal, Alexandros Alexakis, Marc E. Brachet +1
In many simulations of turbulent flows the viscous forces are replaced by a hyper-viscous term in order to suppress the effect of v…
