Direct Numerical Simulation of Turbulence in a Model Solid Rocket Motor
… transport and dissipation in the resolved scale turbulent kinetic energy equation are similar to those observed in turbulent channel flows.

Regeneration mechanisms of organized structures in near-wall turbulence
… decaying and forced turbulence and 3D turbulent channel flows in order to ascertain the sustenance mechanism of near-wall turbulence by investigating the mechanism of streak formation. We found the existence of streaks in quasi-2D flows thus demonstrating that contrary to many proposed …

Structure of turbulent channel flow perturbed by cylindrical roughness elements
… modifications imposed in fully-developed turbulent channel flow by an isolated, wall-mounted circular cylinder. The cylinder height is chosen to specifically extend into the logarithmic layer of the flow in order to study its perturbation of the larger flow scales that embody a significant …

Control of the buffer and logarithmic layers in wall-bounded turbulent flows
… buffer and logarithmic layers in wall-bounded turbulent flows. In the case of buffer-layer control, we examine the effect on near-wall turbulence of displacing the apparent, virtual origins perceived by different components of the overlying flow. This mechanism is commonly reported for …
