Abstract

Experimental studies of combustion stability to the local excess of the component in a dispersed mixture of titanium and carbon powder are presented. It is shown how the spreading of a melt of a low-melting or liquid reaction product affects the stability of combustion transition through a solid and perforated carbon powder target. The melt motion direction with respect to the front propagation direction is revealed. It is indicated that the stability of the combustion transition through the target is determined by thermal interaction between the combustion wave and the target and is not directly related to the convective heat transfer by the melt.

钛与烟灰混合物的燃烧稳定性及组分的局部过量

摘要本文对钛碳粉分散混合物中组分局部过量对燃烧稳定性的影响进行了实验研究。揭示了低熔点或液态反应产物熔体的扩散如何影响通过固体和穿孔碳粉靶的燃烧转变的稳定性。揭示了熔体相对于前传播方向的运动方向。结果表明，燃烧通过靶体的稳定性是由燃烧波与靶体的热相互作用决定的，与熔体的对流换热没有直接关系。

期刊介绍： Combustion, Explosion, and Shock Waves a peer reviewed journal published in collaboration with the Siberian Branch of the Russian Academy of Sciences. The journal presents top-level studies in the physics and chemistry of combustion and detonation processes, structural and chemical transformation of matter in shock and detonation waves, and related phenomena. Each issue contains valuable information on initiation of detonation in condensed and gaseous phases, environmental consequences of combustion and explosion, engine and power unit combustion, production of new materials by shock and detonation waves, explosion welding, explosive compaction of powders, dynamic responses of materials and constructions, and hypervelocity impact.
