Effect of Convergent Angle on different Flow Parameters of a Convergent-Divergent Nozzle

Abstract

Nozzle is defined as a device which is being used to convert the pressure energy into the kinetic energy. It basically controls the mass flow rate, pressure and velocity of the fluid stream. Consisting of three sections convergent, throat and divergent section, this device basically converts subsonic flow into supersonic flow. An extensive study have been conducted by the authors in the past about the divergent angle effect on flow parameters of a C-D (Convergent-Divergent) nozzle. In this paper, detailed study have been done to find the most optimum value of convergent angle of a C-D nozzle for the best flow parameters. Convergent angles under consideration are 15°, 20°, 25°, 30° and 35°.
