Abstract

We present a high resolution, finite-volume Cartesian grid method for simulating potential explosions in nuclear containment structures. The basic method is a Godunov-type method that relies on the solution to non-linear Riemann problems at the interfaces between cells of a uniform Cartesian mesh. We have extended these methods to general quadrilateral and hexahedral adaptively refined grids. Two- and three-dimensional results are presented for a simplified combustion problem in a nuclear containment facility.
