Abstract : A computer program was developed from an existing approximate method for determining the profile of a free expansion jet emanating into a quiescent atmosphere. Inclusion of a scale correlation factor was also a necessary addition to the theory to achieve good compatibility between the approximate and method of characteristic (MOC) solutions. This inclusion gives excellent agreement, in the near-field, with MOC profiles for a wide range of exit Mach numbers, specific heat ratios, nozzle exit angles, and ambient-to-static pressure ratios.
