Dynamics of a vortex column of supercritical fluid across the pseudo-boiling line
Jordi Poblador-Ibanez, Fazle Hussain
The evolution of an axisymmetric vortex column in a weakly compressible supercritical fluid is analysed. A thermal layer is imposed to radially stratify the fluid and uncover effec…

Direct numerical simulation of out-scale-actuated spanwise wall oscillation in turbulent boundary layers
Jizhong Zhang, Fazle Hussain, Jie Yao
Spanwise wall oscillation (SWO) of turbulent boundary layers (TBLs) is investigated via direct numerical simulations over an extended actuation region with oscillation periods up t…
