Direct numerical simulations of turbulent drag reduction via piezoelectric actuation
Amir Amjadimanesh, Aman Kidanemariam, David Chappell +2
We have conducted Direct Numerical Simulations of turbulent half-channel flow over realistic surface deformations at friction Reynolds number . We generated the surface d…
Leveraging unstructured grids for direct numerical simulations of wall turbulence
Amirreza Rouhi, Vishal Kumar, Wen Wu +2
Towards computational cost saving for direct numerical simulations (DNSs) of wall turbulence, we formulate an unstructured grid-generation framework, termed -grid, where the wal…
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…
Spanwise wall forcing can reduce turbulent heat transfer more than drag
Amirreza Rouhi, Marcus Hultmark, Alexander J. Smits
Direct numerical simulations are performed of turbulent forced convection in a half channel flow with wall oscillating either as a spanwise plane oscillation or to generate a strea…
