摘要: A three-dimensional solution-adaptive-grid scheme is described which suitable for complex fluid flows. This method, using tension and torsion spring analogies, was previously developed successfully applied two-dimensional In the present work, a collection of flow fields are used to demonstrate feasibility versatility this concept include an added dimension. Flow considered include: (1) supersonic past aerodynamic afterbody with propulsive jet at incidence free stream, (2) blunt fin mounted on solid wall, (3) over bump. addition generating solution-adapted grids, method can also be effectively as initial grid generator. The utility lies in: optimum distribution discrete points, improvement accuracy, improved computational efficiency, (4) minimization data base sizes, (5) simplified generation.
