The computer programs written in FORTRAN language for the numerical solution of supersonic nozzle flows with condensation are presented. These programs are based on Oswatitschs formulation of one dimensional nozzle flow of ideal gases with subcritical heat addition. Integration of the coupled gasdynamic equations for the flow and the kinetic equations of condensation is done in a stepwise manner in the flow direction downstream from the throat, using a fourth order Runge-Kutta numerical integration algorithm. The nozzle cross-sectional area distribution, and physical properties of the vapor and condensate are written in separate sub-programs. The various forms of rate equations of homogeneous nucleation classical or statistical mechanical and free molecular droplet growth for various ranges of droplet temperatures are written in standard froms as several interchangeable subroutines. Detailed description of the program, flow charts, and sample calculations are included in the appendices. Author
