DOI: 10.1016/j.cja.2018.10.007
Abstract: Abstract The process through which a laminar flow undergoes transition to turbulence is of great fundamental and practical interest. Such a process is hugely complex as there are many diverse routes for a laminar flow… read more here.

DOI: 10.1016/j.oceaneng.2020.108544
Abstract: Abstract The understanding of the internal gaseous flow of artificially ventilated supercavities is developed using a locally homogenous, multiphase computational fluid dynamics model that is benchmarked using experimental data. The solutions indicate that gas leakage… read more here.

DOI: 10.1017/jfm.2018.443
Abstract: Scaling characteristics, essential to the mechanisms of transition in square-prism shear layers, were explored experimentally. In particular, the evolution of the dominant instability modes as a function of Reynolds number were reported in the range… read more here.

DOI: 10.1017/jfm.2020.925
Abstract: Abstract High-resolution simulations of temporally evolving mixing layers, for convective Mach numbers ranging from $M_c=0.2$ to $M_c=2.0$ with density ratios $s=1$ and $s=7$, are analysed to characterize compressibility effects on the structure and evolution of… read more here.

DOI: 10.1017/jfm.2023.316
Abstract: Abstract The perturbation response of small-scale shear layers in turbulence is investigated with direct numerical simulations (DNS). The analysis of shear layers in isotropic turbulence suggests that the typical layer thickness is about four times… read more here.
