A global mass-preserving numerical method for low-Mach-number real-gas flows in closed systems
Sanath Kotturshettar, Gonçalo Alcobia, Pietro Carlo Boldini +2
A mass-preserving low-Mach-number framework is proposed for closed-system real-fluid flows governed by general nonlinear equations of state. The formulation enforces consistency be…
Mean velocity profile in stably stratified turbulent channel flow
Sanath Kotturshettar, Pedro Costa, Rene Pecnik
The Monin-Obukhov Similarity Theory (MOST) is a cornerstone of atmospheric science for describing turbulence in stable boundary layers. Extending MOST to stably stratified turbulen…
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…
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…
Intrinsic compressibility effects in near-wall turbulence
Asif Manzoor Hasan, Pedro Costa, Johan Larsson +2
The impact of intrinsic compressibility effects -- changes in fluid volume due to pressure variations -- on high-speed wall-bounded turbulence has often been overlooked or incorrec…
