Abstract

The development of a finite element method (FEM) based on P2P1 tetra element for the large eddy simulations (LES) of turbulent flows was discussed. A fractional 4-step algorithm was employed to obtain time accurate solution in which the velocity and pressure fields were solved at the same time. Crank-Nicolson method was used for second order temporal discretization and Galerkin method was adopted for spatial discretization. The drag coefficient for the turbulent flow was obtained and it was found that the coefficient decreased as the Reynolds number increased beyond the transition value.
