    An adaptive Cartesian grid generation method for ‘Dirty’ geometry. Z. J. Wang. Corresponding Author. E-mail address: [email protected] The grid generation method is applied here to steady inviscid shock flow computation. A finite difference formulation for the Euler equation using nonet-Cartesian grids is used to treat complex two-dimensional configuration. Results using this approach are shown to be competitive with other methods.

    inviscid flows, it can be a major limitation in simu lations of viscous flows due to cell-Reynolds number constraint on the allowable time step size of explicit schemes. Compared to unstructured and non-boundary-con­ forming Cartesian grids, structured body-fitted grid sys­ tems offer many advantages related to accuracy and. To prove the reliability and capability of the present solution procedure further, the inviscid/viscous results for flows over the NACA airfoil, NACA (12)10 compressor, and one advanced transonic turbine cascade are compared to the numerical and experimental data .

Where the resulting cells intersect bodies, polygonal cut cells are created using modified polygou-clipping algorithms. The grid is stored in a binary tree data structure that provides a natural means of obtaining cell-to-cell connectivity and of carrying out solution-adaptive mesh refinement.

Solution-adaptive refinement of the mesh is then applied to resolve high-gradient regions of the flow. The numerical results presented show the flexibility of this approach and the accuracy.

In this paper, a solution adaptive Cartesian grid solver is developed for 2-D, inviscid perfect gas/equilibrium flows. The Cartesian grid intersects with the body surface, resulting in cut cells.

A new adaptive finite volume conservative cut-cell method that is third-order accurate for simulation of compressible viscous flows is presented.

Solution-adaptive methods based on cutting bodies out of Cartesian grids are gaining popularity now that the ways of circumventing the accuracy problems associated with small cut cells have been developed. Researchers are applying Cartesian-based schemes to a broad class of problems now, and, although there is still development work to be done, it is becoming clearer which problems are best.
