- Аннотация: The study of supersonic jets is important in many engineering applications. Issuing of the supersonic jet from the nozzle may occur in the overexpanded mode, when the pressure in the gas flow from the nozzle outlet is less than the ambient pressure. In a planar overexpanded nozzle flow two oblique shocks are created that start at the nozzle lips and are directed towards the symmetry plane. These incident shocks can reflect either the regular reflection or the Mach reflection. Triple shock configuration can be calculated independently of a boundary problem using a triple-shock theory. The boundaries between regular and two types of Mach reflection (with a positive reflected angle and a negative one) have been calculated analytically for the determining parameters: Mach number of inflow, ratio of specific heats, jet pressure ratio (ambient pressure/pressure at the nozzle exit). The processes of the exhausting of supersonic jet from flat ideal and tapered nozzles have been investigated numerically for two values of specific heat and different initial parameters.
