Research Abstract

This project was planed to apply a Large Eddy Simulation (LES) for various turbulent flows in engineering problems, considering the extension of the computer power in recent years and the limitation of a direct method in the simulation of complex turbulent flows. Although the LES was successfully applied to fundamental studies of turbulence, it was not enough to discuss the capability of LES for engineering problems or the various difficulties in its application to complex flows. The first object was to develop more effective numerical method and more applicable subgrid-scale model for the LES of complex flows. In this approach the following issues were developed and examined ; [A1] a conventional formulation of the 'Dynamic SGS model' which overcomes the drawbacks of previous SGS models in the complex flow simulation ; [A2] a conventional model for the wall boundary condition based on the 'Law of wall' ; [A3] a stable condition for the outlet boundary derive from the convective equation ; [A4] a combined grid technique to suppress numerical errors on the Boundary-Fitted Coordinates ; [A5] a formulation of convective terms by the Finite Element Method. The second part of this project was to investigate the applicability of LES for the engineering problems. A pair of examples - [b1] a backward facing step flow and [b2] a plane turbulent jet - were calculated by the LES.The boundary conditions developed in the above research were applied and validated in these practical objects. Statistical values and typical structures in these flows were predicted well enough to derive the useful information for developing the turbulence models. These results indicated the capability of subgrid scale models and the dependency on the numerical methods. Through these researches the graphical interface was effectively used and a database of the LES results were also displayd by the animations.
