| Abstract: | In this paper, the authos generate the surface unstructured grid for 3-D combination of the body and wing by means of projection transformation. A multinomial method of background grid generation is adopted to control quality and distribution of the unstructured grid. After the surface unstructured grid has been generated, the 3-D unstructured grid for the combination of the body and wing is generated by means of AFM. Improving the quality of the original (3-D) unstructured grid by means of deleting some small and distorted elements and smoothing technique, the Euler equation is solved for the combination of the wing and body by means of the finite-volume method on the unstructured grids. Various methods are used for quick convergence and the results are in correspondence with the experiment data. |
| Keywords: | unstructured grid advancing front method finite-volume method Euler equation wing-body combination |
