On the Coupling of Direct Numerical Simulation and Resolvent Analysis
The present contribution explores the relationship between response and forcing via amplification mechanisms in the Navier–Stokes equations applied to a turbulent pipe flow. A novel numerical method coupling d...

Transient growth and bypass transition in stenotic flow with a physiological waveform
A direct analysis method is applied to compute optimal transient growth initial conditions for physiologically relevant pulsatile flows in a smooth axisymmetric stenosis with 75% occlusion. The flow waveform e...

Turbulent Pipe Flow of Non-Newtonian Fluids
Direct numerical simulation of the weakly turbulent flow of non-Newtonian fluids with shear-thinning rheology are undertaken. Results agree reasonably well with the experimentally determined logarithmic layer ...

Effect of blockage on spanwise correlation in a circular cylinder wake
A short series of experiments was conducted with the aim of assessing the possible effect of tunnel blockage on spanwise correlation lengths measured in the near-wake of a circular cylinder. The results indica...
