First-order buoyancy correction of modal instabilities in stratified boundary layers
Pietro Carlo Boldini, Ryo Hirai, Benjamin Bugeat +1
We present a perturbation-based framework that captures buoyancy effects on modal instabilities in stratified boundary-layer flows within the fully compressible, non-Oberbeck-Bouss…
Direct numerical simulation of complete transition to turbulence with a fluid at supercritical pressure
Pietro Carlo Boldini, Benjamin Bugeat, Jurriaan W. R. Peeters +2
The objective of this work is to investigate the unexplored laminar-to-turbulent transition of a heated flat-plate boundary layer with a fluid at supercritical pressure. Two temper…
Direct Numerical Simulations of K-type transition in a flat-plate boundary layer with supercritical fluids
Pietro Carlo Boldini, Benjamin Bugeat, Jurriaan W. R. Peeters +2
We investigate the controlled K-type breakdown of a flat-plate boundary-layer with highly non-ideal supercritical fluid at a reduced pressure of . Direct numeric…
Transient growth in diabatic boundary layers with fluids at supercritical pressure
Pietro Carlo Boldini, Benjamin Bugeat, Jurriaan W. R. Peeters +2
In the region close to the thermodynamic critical point and in the proximity of the pseudo-boiling (Widom) line, strong property variations substantially alter the growth of modal…
The steady behavior of the supercritical carbon dioxide natural circulation loop
Marko Draskic, Benjamin Bugeat, Rene Pecnik
The steady state behavior of thermodynamically supercritical natural circulation loops (NCLs) is investigated in this work. Experimental steady state results with supercritical car…
Instability in strongly stratified plane Couette flow with application to supercritical fluids
B. Bugeat, P. C. Boldini, A. M. Hasan +1
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…
Low-frequency resolvent analysis of the laminar oblique shock wave / boundary layer interaction
B. Bugeat, J. -C. Robinet, J. -C. Chassaing +1
Resolvent analysis is used to study the low-frequency behaviour of the laminar oblique shock wave / boundary layer interaction (SWBLI). It is shown that the computed optimal gain,…
