Abstract
An aspect of blast wave focusing in water is observed in detail by the schlieren method and the whole process from generation to focusing of the wave is clarified. In the next place are a numerical simulation is performed regarding the two-dimensional focusing of blast waves generated by a spark discharge or a wire explosion in water. Numerical results are shown as bird’s eye views of pressure distribution and computer schlieren diagrams. These diagrams are found to correspond to Schlieren pictures obtained optically.
