Vorticity-dependent and symmetry-preserving LES models
Oscar Cosserat, Dina Razafindralandy, Can Selçuk
Within the Large Eddy Simulation framework, we propose a methodology based on the Lie theory to derive symmetry-preserving turbulence models. We apply this methodology to the incom…
Group theoretic approach and analytical solutions of the compressible Navier-Stokes equations
Dina Razafindralandy, Aziz Hamdouni
A group theoretic analysis of the compressible Navier-Stokes equations of an ideal gas are carried out. The 12-dimensional Lie symmetry group is computed. The commutation table and…
Performance of Borel-Padé-Laplace integrator for the resolution of stiff and non-stiff problems
Ahmad Deeb, Aziz Hamdouni, Dina Razafindralandy
A stability analysis of the Borel-Laplace series summation technique, used as explicit time integrator, is carried out. Its numerical performance on stiff and non-stiff problems is…
A new Hodge operator in Discrete Exterior Calculus. Application to fluid mechanics
Rama Ayoub, Aziz Hamdouni, Dina Razafindralandy
This article introduces a new and general construction of discrete Hodge operator in the context of Discrete Exterior Calculus (DEC). This discrete Hodge operator enables to circum…
Some robust integrators for large time dynamics
Dina Razafindralandy, Vladimir Salnikov, Aziz Hamdouni +1
This article reviews some integrators particularly suitable for the numerical resolution of differential equations on a large time interval. Symplectic integrators are presented. T…
Consequences of Symmetries on the Analysis and Construction of Turbulence Models
Dina Razafindralandy, Aziz Hamdouni
Since they represent fundamental physical properties in turbulence (conservation laws, wall laws, Kolmogorov energy spectrum, ...), symmetries are used to analyse common turbulence…
