Theory of Particle Combustion at High Pressures

Conventional theories of particle combust ion become inaccurate when t h e gas pressure rises, and are complete ly useless above t h e critical pressure. The paper discusses the transient effects, neglected in conventional theories, which dominate the burning process at h igh pressures. A quanti tat ive theory is presented, valid for these condit ions , of the t i m e variations of flame radius, burning rate and combust ion efficiency.
