Converging cylindrical detonation wave: numerical modeling and experiment

Numerical modeling of formation and propagation of detonation wave with concave curvature was conducted in present work. The modeling follows experiments where detonation of cylindrical explosive charge is initiated by multiple 3D-printed initiation modules. Specific experiments were used to adjust parameters of the equation of state of charge explosive and of lenses material employed. The modeling has revealed main features in performance of single initiation module and of an initiation module installed in an experimental setup. Possibility of formation of “smooth” converging detonation wave was confirmed empirically.
