Статья посвящена численному решению задачи о горении порошкового металлического топлива в камере сгорания с закрученным потоком. Представлена физико-математическая модель течения воздушной взвеси алюминиевого порошка закрученным потоком в цилиндрической камере сгорания с внезапным расширением. Физико-математическая постановка задачи основана на подходах механики двухфазных реагирующих сред. Решение проводилось методом распада произвольного разрыва. Приведены результаты численного параметрического исследования особенностей горения воздушной взвеси алюминиевого порошка в зависимости от ее состава, осевого расхода смеси на входе в камеру сгорания и значения скорости закрутки.
