Abstract : The reflection of a hemispherical imploding shock wave in argon was studied in the region very close to the centre. Two aspects, which could not be studied by classical analysis near the centre, were the effect of a cold wall upon the reflection and multi-body collisional effects. The effect of the cold wall was examined using a Monte-Carlo technique and comparing the results obtained when the wall was treated as specularly reflective and diffuse reflective. It was found that a substantial difference occurred near the centre but it appeared that this effect would be rapidly damped. The multi-body collisional effects were studied using a modified form of molecular dynamics. (Author)
