Fortran IV (IBM 7090) Program for the Design of Contoured Axisymmetric Nozzles for High Temperature Air

Abstract

A computer program is presented for designing contoured axisymmetric nozzles when the supply air temperature is high enough to produce real gas effects. The real gas properties of high temperature air in thermodynamic equilibrium are computed using empirical equations and assuming that the air undergoes an isentropic expansion. These properties are used to determine the potential core contour by solving the inviscid flow equations by the method of characteristics. The turbulent boundary layer growth is computed from a numerical integration of the momentum integral equation and is added to the potential core to obtain the nozzle contour. The heat transfer rate is calculated from a form of Reynolds analogy. The computer program covering these phases of nozzle design is presented with the instructions necessary for using it.
