Abstract

A computational and experimental study of the passage of a gasless combustion wave through a wedge-shaped inert obstacle was performed. The stability of the transient combustion process to a change in the thermophysical and geometric parameters of the obstacle and the energy-kinetic parameters of chemically active layers was studied. By the region of stable transient combustion process is meant the range of parameters in which the passage of the combustion wave through the contact boundary ends with the establishment of its steady-state propagation regime in the ignited composition. The dynamics of transient combustion under near-critical conditions of its existence was investigated.

燃烧波通过楔形障碍物时的热能积累

摘要

计算和实验研究了无气燃烧波通过楔形惰性障碍物的过程。研究了瞬态燃烧过程对障碍物的热物理和几何参数以及化学活性层的能量动力学参数变化的稳定性。稳定瞬态燃烧过程的区域是指参数范围，在该范围内，燃烧波通过接触边界的过程随着在被点燃的成分中其稳态传播机制的建立而结束。研究了瞬态燃烧在其存在的近临界条件下的动力学。
