Implementation of Adaptive Hybrid Grids for 3-D Turbulent Flows
نویسنده
چکیده
The paper presents an implementation of a one-equation turbulence model with 3-D adaptive hybrid grids. The grids are composed of prismatic elements close to the body surface, and tetrahe-dral elements elsewhere. An adaptive redistribution scheme is also presented which results in increased resolution of boundary layers and wakes. Use of prisms is extended to resolve both single and multiple wakes. The robustness of the developed turbulence model implementation and the effectiveness of the hybrid grid are tested by performing transonic and supersonic ow simulations for the ONERA M6 wing and the High Speed Civil Transport aircraft.

متن کاملMultiscale Methods for the Simulation of Turbulent Flows
In this paper we apply the finite difference method on adaptive sparse grids [9] to the simulation of turbulent flows. This method combines the flexibility and efficiency of finite difference schemes with the advantages of an adaptive approximation by tensor product multiscale bases. We shortly discuss the method. Then, we present numerical results for a simple linear convection problem for a v...
متن کاملPartitioning and Dynamic Load Balancing of Adaptive Hybrid Grids for Large-Scale Turbulent Flow Simulations
A new partitioning method for complex 3-D hybrid prismatic/tetrahedral meshes is presented, The method uses an orthogonal recursive bisection approach on a special octree corresponding to the hybrid grid. The octree is generated automatically and handles any type of 3-D geometry and domain connectivity. It is employed for partitioning of static, as well as dynamic adaptive meshes. The method yi...
