A Dynamic α Model for the Lagrangian Averaged Navier-Stokes-α Equations
A dynamic α model for the isotropic incompressible LANS-α equations is proposed in this investigation. To derive this model, the incompressible Navier-Stokes equations are Helmholtz-filtered at the grid and test filter levels. A Germano type identity is derived by comparing the filtered subgrid scale stress terms with those given in LANS-α equations. Considering a constant value of α and averag...
متن کاملDynamic Modeling of Α in the Isotropic Lagrangian Averaged Navier-stokes-α Equations
A dynamic procedure for the Lagrangian Averaged NavierStokes-α (LANS-α) equations is developed where the variation in the parameter α in the direction of anisotropy is determined in a self-consistent way from data contained in the simulation itself. In order to derive this model, the incompressible NavierStokes equations are Helmholtz-filtered at the grid and a test filter levels. A Germano typ...

متن کاملThe Anisotropic Lagrangian Averaged Euler and Navier-Stokes Equations
The purpose of this paper is twofold. First, we give a derivation of the Lagrangian averaged Euler (LAE-α) and Navier-Stokes (LANS-α) equations. This theory involves a spatial scale α and the equations are designed to accurately capture the dynamics of the Euler and Navier-Stokes equations at length scales larger than α, while averaging the motion at scales smaller than α. The derivation involv...
متن کاملLagrangian Averaged Navier-stokes-alpha (lans − Α) Equations for Modeling Turbulence
Lagrangian averaging (LA) is producing new ideas and methods for the construction of novel subgrid models for momentum, energy and scalar transport in turbulence. LA is applied at fixed Lagrangian fluid label, rather than at fixed spatial location, as in Eulerian averaging and filtering for RANS and LES equations, respectively. Instead, LA is performed in a frame of motion that follows along wi...
