Abstract

Overset Unstructured Grid method is extended to the multiple bodies that are in contact with each other. In this paper, treatments of nodes in the overlapping regions of two bodies in contact are discussed in detail. The developed Overset Unstructured grid method is applied to the ONERA M5 body/wing case, ONERA M6 store separation case, and, NAL experimental supersonic airplane/booster separation case. In each case, there are two bodies in contact and the calculation is performed by Euler code. The calculation results clearly show smooth transitions of the contour lines between two bodies. In the ONERA M6 and NAL airplane/booster cases, the separating simulation from connecting configuration is performed.
