On cylindrically converging shock waves shaped by obstacles
2008 (English)In: Physica D: Non-linear phenomena, ISSN 0167-2789, Vol. 237, no 14-17, 2203-2209 p.Article in journal (Refereed) Published
Motivated by recent experiments, numerical simulations of cylindrically converging shock waves were performed. The converging shocks impinged upon a set of 0-16 regularly space obstacles. For more than two obstacles the resulting diffracted shock fronts formed polygonal shaped patterns near the point of focus. The maximum pressure and temperature as a function of the number of obstacles were studied. The self-similar behavior of cylindrical, triangular and square-shaped shocks was also investigated.
