• Supersonic jet flow-fields from a two-dimensional sonic nozzle are computed using the piecewise linear method. The sonic radius for a two-dimensional source flow is estimated using the numerical results. It is shown that the flow properties on the jet axis can be approximated by the two-dimensional source flow at large distances from the nozzle. The distance of the normal shock from the nozzle increases with the stagnation to ambient pressure ratio, but is somewhat larger than experiments.
