A numerical method was developed for predicting the pressure-time variation of a sonic boom wave acting on
an arbitrary building. The conservation laws for fluid flow were greatly simplified with weak wave approximations
and then the numerical technique developed by the Russian mathematician, V.V. Rusanov, was extended to three dimensions
and applied. A treatment for two-dimensional as well as three-dimensional building corners was developed.
For the first time, Rusanov's technique extended to three dimensions was applied to a sonic boom wave/structure
interaction problem.
A computer program was written for a sample problem , involving a plane wave oblique to all building surfaces.
There were 9,261 mesh points in the field (a 21-sided cube), and the computation was performed on an IBM 360/65 digital
computer. The results seem to be physically correct.
