THREE-DIMENSIONAL NUMERICAL SIMULATIONS OF BLAST WAVE PROPAGATION INDUCED BY IMAGINARY EXPLOSIONS AT THE LAUNCH PAD OF THE TANEGASHIMA SPACE CENTER IN THE INTEREST OF SAFETY ANALYSIS

摘要

The paper describes a numerical model for computing blast waves' propagation over realistic terrains with human-made structures on it. The solver is based on locally-adaptive unstructured tetrahedral grids and high-resolution shock-capturing schemes and optimized for vector supercomputers. In particular, we show results of a single run considering an imaginary accidental explosion at the launch pad of the Tanegashima Space Center and covering both the middle-range blast wave interaction with some engineering structures and the long-range propagation of the wave.
