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…
Scaling of wall pressure and the peak of streamwise turbulence intensity in compressible wall flows
Asif Manzoor Hasan, Pedro Costa, Johan Larsson +1
This paper develops scaling laws for wall-pressure root-mean-square (r.m.s.) and the peak of streamwise turbulence intensity, accounting for both variable-property and intrinsic co…
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…
Entropy-Stable Model Reduction of One-Dimensional Hyperbolic Systems using Rational Quadratic Manifolds
Robin Klein, Benjamin Sanderse, Pedro Costa +2
In this work we propose a novel method to ensure important entropy inequalities are satisfied semi-discretely when constructing reduced order models (ROMs) on nonlinear reduced man…
