Abstract

A solution-adaptively moving-grid method for unsteady shocked flows is presented in this paper. An elliptic system for solution-adaptive gridding and a finite-volume method formulated on space-time control volume for compressible flow solution are combined through an inner iteration process and solved simultaneously at every time step. The method is derived for two-dimensional space and validated using simple test problems. Application to a cylindrical implosion problem showed a promising feature of the method.
