Аннотация
The problem of ignition of a condensed substance by single particles heated up to high temperatures is solved within the framework of the two-dimensional heat-transfer model. Numerical studies are performed for typical materials: polyvinyl nitrate and carbonic particles. Regimes of ignition of a condensed substance by a single particle at relatively low temperatures are adequate in terms of the ignition delay to regimes of heating of the condensed substance by a gas flow without particles; at high temperatures, they correspond to regimes of heating by a metal plate with a fixed temperature. In a certain (rather narrow) range of particle temperatures, the use of the two-dimensional heat-transfer model yields ignition-delay values substantially different from other regimes.
