Transient growth mechanisms of low Reynolds number flow over a low-pressure turbine blade
AS Sharma, N Abdessemed, SJ Sherwin +1
A direct transient growth analysis for three-dimensional perturbations to flow past a periodic array of T-106/300 low-pressure turbine fan blades is presented. The methodology is b…
Model-based scaling of the streamwise energy density in high-Reynolds number turbulent channels
Rashad Moarref, Ati S. Sharma, Joel A. Tropp +1
We study the Reynolds number scaling and the geometric self-similarity of a gain-based, low-rank approximation to turbulent channel flows, determined by the resolvent formulation o…
Relaminarisation of Re_τ = 100 channel flow with globally stabilising linear feedback control
A S Sharma, J F Morrison, B J McKeon +3
The problems of nonlinearity and high dimension have so far prevented a complete solution of the control of turbulent flow. Addressing the problem of nonlinearity, we propose a flo…
On coherent structure in wall turbulence
A S Sharma, B J McKeon
A new theory of coherent structure in wall turbulence is presented. The theory is the first to predict packets of hairpin vortices and other structure in turbulence, and their dyna…
