The influence of air supply tothe central duet of the atomizer on the configuration of the reverse current zone and the characteristics of the spraycone is revealed. Comparative study of spray cones behind frontal devices of various types is carried out. Data onspraying liquid films from plate surfaces and the distribution of concentration pulsations in the flow are obtained.</p>Combustion chamberatomizerspray conevisualizationКамера сгоранияфорсункафакел распыливаниявизуализация
