A Compressible Turbulence Model for Pressure—Strain

open access: yesFluids, 2022
This work focuses on the performance and validation of compressible turbulence models for the pressure-strain correlation. Considering the Launder Reece and Rodi (LRR) incompressible model for the pressure-strain correlation, Adumitroaie et al., Huang et

Development of High-Fidelity Numerical Methodology for Prediction of Vehicle Interior Noise Due to External Flow Disturbances Using LES and Vibroacoustic Techniques

open access: yesApplied Sciences, 2022
A pleasant and quiet cabin in driving a car is one of the most critical factors affecting a customer’s choice in a market. As the traditional noise sources such as power trains become less, the relative contribution of aerodynamic noise to the interior ...

Numerical solution of inviscid and viscous flow around the profile

open access: yesEPJ Web of Conferences, 2015
This work deals with the 2D numerical solution of inviscid compressible flow and viscous compressible laminar and turbulent flow around the profile. In a case of turbulent flow algebraic Baldwin-Lomax model is used and compared with Wilcox’s k-ω model ...

The discontinuous Galerkin method for the numerical simulation of compressible viscous flow

open access: yesEPJ Web of Conferences, 2014
In this paper we deal with numerical simulation of the compressible viscous flow. The mathematical model of flow is represented by the system of non-stationary compressible Navier-Stokes equations.

Quasi-neutral limit of the flow of a chemically reacting gaseous mixture for ionic dynamics

open access: yesElectronic Journal of Differential Equations, 2019
In this article we consider the quasi-neutral limit of the compressible flow of a chemically reacting gaseous mixture in the periodic domain $\mathbb{T}^3$ with the well-prepared initial data.

Compressible Navier-Stokes flow in Schrödinger-type variables

open access: yesPhysical Review Research
Fluid equations are nonlinear, dissipative, and non-Hamiltonian, which makes their relation to Schrödinger evolution and quantum algorithms nontrivial. We derive an exact Eulerian Cole-Hopf-type reformulation of isothermal compressible Navier-Stokes (NS)
