✦ Synopsis

Two different numerical schemes are proposed for the study of the behavior of a viscous incompressible fluid in a turbulent regime using the M.P.P. model. They differ in their treatment of both velocity and turbulent kinetic energy at the time discretization stage. The first, a Gear scheme, is fully implicit, while the second is of the alternate direction type. In both, the Lagrangian coordinate is calculated by applying an explicit Lax-Wendroff scheme. Various numerical experiments showed good agreement between the two schemes.
