Basics : Turbulent flow

This LS-DYNA simulation shows a turbulent flow input deck. The fluid and boundary conditions give a Reynolds number of 50 000 making the flow turbulent and prompting the use of a turbulence model. The default configuration uses a RANS realizable model. The boundary layer mesh has been chosen in accordance, to yield an approximate Y+ value of 30. Several other turbulence models can be tried and the boundary layer mesh changed accordingly. The user can study the length and effects of the recirculation zone over the thick plate.
