A (k-epsilon) model of turbulent flow
Abstract
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-epsilon) 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 the other, computing the magnitude of the turbulent viscosity from the turbulence kinetic energy and the dissipation rate.
