| Abstract: | The dependence of the flow coefficient of a gas jet ejected from an orifice/nozzle into a subsonic/transonic cross-flow on
the flow and the jet Mach numbers, the off-design ratio, the nozzle inclination angle, β, and other determining parameters
is considered. The physical nozzle flow pattern is constructed on the basis of experimental data obtained for 0.3< M∞<1.75 and β=60°, 90°, and 120°. The results of measuring the pressure upstream and downstream of the orifice and on the windward
and leeward orifice generators are presented. It is shown that the flow rate coefficient of a jet ejected into a cross-flow
may exceed that of a similar jet outflowing into a flooded space.
