Excitation and stability of nonlinear compressible Görtler vortices and streaks induced by free-stream vortical disturbances
Dongdong Xu, Pierre Ricco, Elena Marensi
We study the generation, nonlinear development and secondary instability of unsteady Görtler vortices and streaks in compressible boundary layers exposed to free-stream vortical di…
Laminarising turbulent pipe flow by linear and nonlinear optimisation
Shijun Chu, Ashley P. Willis, Elena Marensi
It has been observed that flattening the mean velocity profile of pipe flow by body force can laminarise turbulence, a promising means to reduce frictional drag substantially. To e…
The minimal seed for transition to convective turbulence in heated pipe flow
Shijun Chu, Ashley P. Willis, Elena Marensi
It is well known that buoyancy suppresses, and can even laminarise turbulence in upward heated pipe flow. Heat transfer seriously deteriorates in this case. Through a new DNS model…
