Popis:	It is of special interest in some conventional chemical technologies to provide either fast mixing of reagents or rapid quenching of final chemical product. One of most promising techniques to achieve it is mixing of multiple jets radially injected in crossflow (JIC) of cylindrical duct when jets impinge and form a jet flowing towards a crossflow. As result of an interaction of counter-flowing jet and confined crossflow, a recirculation flow zone (RFZ) upstream of jets injection plane (JIP) is formed (see Fig.1). Of valuable importance is to reveal upstream behavior of developed counter-flowing jet in confined crossflow in order to estimate an extreme RFZ size where jets are diluted and mixed under non-equilibrium conditions.
