Abstract: | The principle of focusing compression waves by their reflection from nonflat surfaces is well-known. The invention in [1] postulates for this purpose the use in a pulsed hydrojet of a piston with a specially shaped surface. In this paper, the use of focusing is investigated numerically for the production of superjets.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 5, pp. 153–156, September–October, 1976. |
