METHOD OF FORMING JET AND NOZZLE-INJECTOR FOR REALIZATION OF THIS METHOD

摘要

FIELD: hydro-gas dynamics; fire-fighting equipment; decontamination equipment; chemical industry; flying vehicles and engines. SUBSTANCE: longitudinal flow is passed through longitudinal passage in nozzle- injector this flow is expanded due to formation of at least one peripheral transverse flow through discharge of part of working medium via one passage made in form of hole in wall of longitudinal passage which is made in form of slot intersecting with cut of longitudinal passage outlet forming attached flow at pressure in near- wall layer equal to or more than product of magnitude equal to 1-100% of Sommerfild criterion by magnitude of surrounding pressure where resultant jet of preset form and sizes is generated. EFFECT: enhanced efficiency. 15, 3 dwgE
