  The cylindrically converging shock wave was numerically simulated by solving
the Euler equations in cylindrical coordinates with TVD scheme and MUSCL
approach, using Roe's approximate Riemann solver and super-bee nonlinear
limiter. The present study used the in house code developed for this purpose.
The behavior of the solution in the vicinity of axis is investigated and the
results of the numerical solution are compared with the computed data given by
Payne, Lapidus, Abarbanel, and Goldberg, Sod, and Leutioff et al.
