Effect of Highly Concentrated Energy Fluxes on Materials

Results of investigation of the characteristics of an erosion plasma flow directed to an obstacle are presented. Stable quasi-stationary spherical plasma formations existing for more than 50 μsec were obtained for the first time. It is shown that the parameters, length, and localization of the cumulative zone in this plasma can be controlled by changing the dynamic characteristics of the incident flow.

Keywords
