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…
Variable-property and intrinsic compressibility corrections for turbulence models using near-wall scaling theories
Asif Manzoor Hasan, Alex Jose Elias, Florian Menter +1
We introduce a novel approach to derive compressibility corrections for Reynolds-averaged Navier-Stokes (RANS) models. Using this approach, we derive variable-property corrections…
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…
