Transient growth in diabatic boundary layers with fluids at supercritical pressure

PC Boldini, B Bugeat, JWR Peeters, M Kloker… - Physical Review …, 2024 - APS
In the region close to the thermodynamic critical point and in the proximity of the
pseudoboiling (Widom) line, strong property variations substantially alter the growth of …

Instability in strongly stratified plane Couette flow with application to supercritical fluids

B Bugeat, PC Boldini, AM Hasan… - Journal of Fluid …, 2024 - cambridge.org
This paper addresses the stability of plane Couette flow in the presence of strong density
and viscosity stratifications. It demonstrates the existence of a generalised inflection point …

Direct Numerical Simulations of K-type transition in a flat-plate boundary layer with supercritical fluids

PC Boldini, B Bugeat, JWR Peeters, M Kloker… - arXiv preprint arXiv …, 2024 - arxiv.org
We investigate the controlled K-type breakdown of a flat-plate boundary-layer with highly
non-ideal supercritical fluid at a reduced pressure of $ p_ {r,\infty}= 1.10$. Direct numerical …
