The features of the foam formation procedure in the foam generative devices of ejector-type

Abstract

On the basis of researches of foam formation process in the foam generative devices the features of foam formation
have been determined in the foam generative devices of ejector-type. The regulations of dependence for
volumetric ejection at various pressure in the suction chamber and relative change of pressure and velocity have
been grounded and they are depicted in the jump depending on the ejection rate at various values Makh's number
and losses of flow rate for formation of fluid-air mixture due to ejection coefficient at different pressure values in the
suction chamber etc. The graph of static pressure distributing was built though the length of foam generative ejector
according to different values of ejection coefficient. The results of the research enable to choose the most efficient
mode of fluid and gas flow in the foam generative device that will allow uniformly to saturate liquid with gas and
with further formation fine-graded disperse foam flow.
