| Abstract | The three-dimensional, primitive equations of motion have been solved numerically for the case of isotropic box turbulence and the distortion of homogeneous turbulence by irrotational plane strain at large Reynolds numbers. A Gaussian filter was applied to governing equations to define the large scale field. This gives rise to additional second order computed scale stresses (Leonard stresses). The residual stresses are simulated through an eddy viscosity. 16x16x16 and 32x32x32 uniform grids were used, with a fourth order differencing scheme in space and a second order Adams-Bashforth predictor for explicit time stepping. The results were compared to the experiments and statistical Information was extracted from the computer generated data. |
