Reynolds number dependence of length scales governing turbulent flow separation with application to wall-modeled large-eddy simulations
Rahul Agrawal, Sanjeeb Bose, Parviz Moin
This article proposes a Reynolds number scaling of the required grid points to perform wall-modeled LES of turbulent flows encountering separation off a solid surface. Based on com…

An extension of Thwaites method for turbulent boundary layers
Rahul Agrawal, Sanjeeb T. Bose, Kevin P. Griffin +1
Thwaites (1949) developed an approximate method for determining the evolution of laminar boundary layers. The approximation follows from an assumption that the growth of a laminar…

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,…
