The article deals with the influence of cylindrical site extent in the jet nozzle’s minimum section on coefficient of discharge which was evaluated according to the geometrical characteristics with the modern methods of computing hydrodynamics. It shows the dependences of influence of extent on discharge coefficient for sound and supersonic nozzles at various taper angles. It gives idiosyncrasies of influence of a rounding off upon the transition to the cylindrical site.
Keywords: jet nozzle, discharge coefficient, gas dynamics, modeling.
