Résumé :
|
A two-equation model of turbulence is employed where the transport of turbulence kinetic energy and the dissipation rate are depicted by transport type equations, i.e., the two-equation model of turbulence. A finite-element discretization of the (k-E) turbulence model is described that relies on the sequential approach in the solution. As in finite-difference procedures, velocity and pressure are uncoupled and the equations are solved one after ther other, computing the magnitude of the turbulent viscosity from turbulence kinetic energy and dissipation rate.
