Euler solutions with a multi-block structured code 13; 13;

Multiblock schemes enhance the scope of application of computational fluid dynamics to present-day complex configurations. With multiblock grid generation, embedded grids, and different equations in different domains, it should be possible to resolve the main features of flow over a complete aircraft with a grid containing about a million cells. Basic steps in the coding of multiblock schemes are described. Euler solutions for the vortex- dominated flow over a cropped delta wing are presented. These solutions show separation from the leading edge and formation of a leeside vortex. (B.J.
