AbstractThe moving-coordinate method presented by the authors is a methodology where physical phenomena are observed from the accelerating frame attached to a moving body. In this study, the moving-coordinate method is generalized by newly including both the translational and rotational motions of the frame. As the moving body is observed to be stationary in the moving-coordinate method, the present method has advantages that there is no regeneration of the grid around the object and no calculation error induced by moving grids. The governing equations of the moving-coordinate method are derived for the conservation laws of mass, momentum, and total energy, where the source terms are added to the conventional conservation laws of fluid. Further, the transformations of momentum and total energy between the inertial frame and the moving frame are presented. The present method was applied to supersonic flows around a rectangular parachute model, whose motion is represented by the momentum balance. The computational results showed the self-excited motions of the model.
