Non-equilibrium effects in turbulent boundary layers over riblets: DNS of step changes in surface texture
Vishal Kumar, Melissa Kozul, Wen Wu +2
We computationally study the response of zero-pressure-gradient (ZPG) turbulent boundary layers (TBLs) to streamwise step changes from a smooth wall to riblets (SM_RI), and vice ve…

Projection-based stabilization for high-order incompressible flow solvers
Antonio Blanco-Casares, Vishal Kumar, Daniel Mira +1
This work presents a novel stabilization strategy for the Galerkin formulation of the incompressible Navier-Stokes equations, developed to achieve high accuracy while ensuring conv…
