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…

Aerodynamically-driven rupture of a liquid film by turbulent shear flow
Melissa Kozul, Pedro S. Costa, James R. Dawson +1
The rupture of a liquid film due to co-flowing turbulent shear flows in the gas phase is studied using a volume-of-fluid method. To simulate this multiphase problem, we use a simpl…
