The quest for reductions in fuel consumption and CO 2 emissions in transport has been a
powerful driving force for scientific research into methods that might underpin drag-reducing …

Spanwise wall oscillation is an easily implemented active control scheme. It can delay the
transition to turbulent flows in incompressible boundary layers under appropriate control …

The temporal linear stability of plane Poiseuille flow modified by spanwise forcing applied at
the walls is considered. The forcing consists of a stationary streamwise distribution of …

The drag-reduction mechanism of spanwise wall oscillation in a turbulent channel was
investigated as an extension of the work of Yakeno et al.[“Modification of quasi-streamwise …

In this paper, we study the effect of lateral wall vibrations on the excitation and evolution of
non-modal perturbations in hypersonic boundary layers subject to low-frequency freestream …

Global linear stability analysis is performed for a coupled fluid–structure-interaction problem
of a NACA0012 airfoil at transitional Reynolds numbers to investigate the phenomenon of …

Turbulence control in the form of a streamwise travelling wave of transverse wall motion was
studied numerically by employing direct numerical simulations (DNS). Both total and phase …

In this thesis, we have explored the temporal and spatiotemporal stability analyses offree
shear, viscoelastic flows in the limit of low to moderate Reynolds number (Re) and …
