The separation effect of the nozzle process was analysed numerically based on the assumption that the gaseous flow from a nozzle outlet could be regarded as a continuum and that the pressure diffusion formed in the jet caused isotope separation.
An approximate expression was derived for the separation effect, as a function of cut and Mach number. In order to estimate the separation effect, it was necessary as a first step to solve the equation of motion expressed by a modified hodograph, using an analogue computer.
The calculated results gave the fundamental characteristics of this separation process, for example, the relation between the separation effect and the cut whose value was dependent on Mach number. In particular, it was indicated that the separation effect was maximum when the Mach number was infinite.
