Weak burning and gas-phase ignition about a carbon particle in an oxidizing atmosphere

Research output: Contribution to journalArticle

Abstract

The departure from frozen flow behavior about a carbon particle in an oxidizing atmosphere, has been discussed in order to obtain the burning rate M over a wide range of the Damkohler number Dg(rep-resenting either the particle size or the ambient pressure). The frozen limit (Dg→0) leads to values of M ranging up to M2, the maximum burning rate corresponding to diffusion controlled heterogeneous reactions. By contrast, for finite values of Dgwe find that the burning rate is limited by M1g<M2. The maximum Damkohler number Dg° given by an explicit formula, corresponds to gas phase ignition.
