Abstract

It is known that the interaction between jets of high-temperature gas and various materials may involve the ablation of those materials as a result [1] of chemical erosion (in the presence of chemically active components in the jet), partial melting in case the level of heat loads is sufficient for heating the material to the temperature T exceeding its temperature Tm, and the evaporation of the melt. The traditional concepts of the mechanism of ablation of materials under conditions of interaction with high-temperature gas flows alone cannot provide an explanation of the experimental results of [2, 3], which corroborate the promise held by the use of high-temperature heterogeneous jets for cutting and punching various structural materials (including metals and alloys). This study is aimed at more specifically defining (as a result of numerical investigation) the mechanism of destruction of some structural materials under conditions of interaction with a jet of high-temperature gas.
