A Two-dimensional/Axisymmetric Nozzle Design Code Using the Irrotational Method of Characteristics (IMOCND)

About this technology

Overview

The innovation is a computer program which can be used to design two-dimensional or axisymmetric nozzles having uniform or non-uniform (Mach number and/or flow angle) supersonic inflow. If possible, the computer program generates a nozzle contour which produces supersonic, shock-free, uniform flow at the nozzle exit. (Certain non-uniform inflow conditions may create a shockwave which violates the potential flow assumption, stopping the program.) The program also give the user control over the geometry at inflow and in the expansion region of the nozzle.
