To quantify the two revealed characteristics of the flame dynamics—the dependence of the average flame velocities on time and the dependence of the initial flame velocity on the stoichiometry of the initial hydrogen–air mixture—we proposed time and stoichiometric scaling relations. The first relation approximates the dependence of the path of the flame front in hydrogen–air mixtures with an initial hydrogen concentration exceeding a certain critical value. The second relation approximates the dependencies of the initial flame front velocities on the hydrogen concentration. The general relationships for topologically different types of ultralean hydrogen–air flames can be interpreted as additional evidence of the presence of a general mechanism for the transition from discrete fronts of isolated drifting ball flames to a quasi-continuous deflagration flame front through a cascade of bifurcations.</p></abstract><trans-abstract xml:lang="ru"><p>С помощью метода последовательно инвертированного проецирования изучена динамика ультрабедных водородо-воздушных пламен, свободно распространяющихся в горизонтальной цилиндрической ячейке Хеле - Шоу. Для количественной оценки двух выявленных характеристик динамики пламени - зависимости усредненных скоростей пламени от времени и зависимости начальной скорости пламени от стехиометрии исходной водородо-воздушной смеси - были предложены временное и стехиометрическое скейлинговые соотношения. Первое соотношение аппроксимирует зависимость пути фронта пламени в водородо-воздушных смесях с начальной концентрацией водорода, превышающей некоторое критическое значение. Второе соотношение аппроксимирует зависимости начальных скоростей фронта пламени от концентрации водорода. Наличие единых соотношений для топологически различных типов ультрабедных водородо-воздушных пламен может быть интерпретировано как дополнительное свидетельство наличия единого механизма перехода от дискретных фронтов изолированных шаровых пламен к квазинепрерывному фронту дефлаграционного пламени через каскад бифуркаций.</p></trans-abstract><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>A. von Humboldt and J.
