С помощью программы FDS (version 5) проведено компьютерное моделирование начального этапа стационарного пламенного пожара в закрытом помещении. Показано, что в стационарном по массовой скорости горения пожаре присутствуют стационарный и нестационарный этапы по тепловыделению, длительности которых зависят от мощности и высоты расположения источника пожара. Нестационарный этап характеризуется нерегулярными по амплитуде и длительности пульсациями тепловыделения, обусловленными возникновением пламенного горения в объеме дыма

A computer simulation of the initial stage of stationary flame fire in an indoor area has been made with the help of FDS software (version 5). It has been shown that stationary and non-stationary heat release stages are present in a stationary fire according to mass burning rate. Duration of these stages depend on fire source intensity and its level. Non-stationary stage is characterized heat liberation pulsations which are irregular in amplitude and duration. The pulsations are caused by uprising of flame burning in the smoke scope.
