A study of compressibility effects on structure and evolution a sheared homogeneous turbulent flow is carried out using rapid distortion theory (RDT). The focus this paper consists in validating RDT code by considering the direct numerical simulation (DNS) results Simone [Simone, Coleman Cambon, Fluid Mech. 330, 307 (1997)]. We will use to clarify physics compressible flows. An analysis behavior different terms appearing kinetic energy Reynolds stress equations permit well identify which...
Equilibrium states of homogeneous compressible turbulence subjected to rapid shear is studied using distortion theory (RDT). The purpose this study determine the numerical solutions unsteady linearized equations governing double correlations spectra evolution. In work, RDT code developed by authors solves these for flows. Numerical integration carried out a second-order simple and accurate scheme. two Mach numbers relevant flow are turbulent number Mt, given root mean square velocity...
This paper investigates the effect of initial conditions characterized by compressibility turbulence on changes in scalar such as density, temperature, and pressure within framework rapid distortion theory (RDT) case non-isentropic turbulence. study is a follow-up basic work carried out A.

Res. 52, 025501 (2020)] RDT was used to examine behavior root mean square (rms)...
We identify storage coefficient and hydraulic transmissivity in groundwater flow governed by a linear parabolic equation. Both parameters are assumed to be piecewise constant functions space. The unknowns the values as well geometry of zones where these coefficients constant. goal this work is improve an adaptive parameterization approach for solving inverse problem parameter estimation. define posteriori error estimators depending on refine computing mesh during adaptative parametrization algorithm.
The aim of this work is to simulate compressible homogeneous non-isentropic turbulence initially isothermal and submitted pure shear using Rapid Distortion Theory (RDT) method. It thus completes the study Riahi Lili (2023). degree which RDT can be used analyze compressibility effect, in particular, on thermal properties turbulence, verified. We find that initial gradient Mach number, a parameter characterize compressibility, has an effect thermodynamic variables behaviors, especially for...
In this study, we use Rapid Distortion Theory (RDT) to simulate compressible homogeneous sheared turbulence in the non-isentropic hypothesis of fluctuating flow. This linear model permits us analyze compressibility effects on structure and thermal properties turbulence. The analysis concerns root mean square (rms) thermodynamic variables fluctuations correlations between them. RDT results are obtained for isothermal isobaric initial conditions. A comparison these is carried out different...
