Realizable Dynamic Large Eddy Simulationet al. Phys. Fluids A 3:1760–1765, 1991, [.]. This is a method for the calculation of model parameters as functions of time and space as the simulation progresses. It avoids empirical treatment of model parameters such as damping or wall modeling near the wall boundaries. On the other hand, dynamic

The Dynamic Smagorinsky Model in , Pseudo-Spectral LES of Decaying Homogeneous Isotropic Turbulence rojection due to the LES grid. The truncation of the complete field . (experimental or from direct numerical simulation, DNS) to the much coarser LES grid corresponds to the incomplete LES field and is noted .. Assuming perfect numerics, the “effective subgrid-scales (SGS) stress” is then obtained a

Springer Lexikon Kosmetik und KörperpflegeThe Direct Numerical Simulation of turbulent flows (DNS) has proved itself, over the years, an extremely valuable tool to investigate the fundamental properties of turbulence, often rivalling experiments by virtue of its accuracy and of the insight it offers to the investigator (Moin and Mahesh, Ann Rev Fluid Mech 30:539–578, 1998) [.].

Discrete Conservation of Helicity in Numerical Simulations of Incompressible Turbulent FlowsHelicity is the scalar product between velocity and vorticity and, just like energy, its integral is an inviscid invariant of the 3D incompressible Navier–Stokes equations, .where . is the non-linear convective term and Re is the Reynolds number.
