Supersonic freejets have been studied as a fundamental phenomenon of the supersonic fluid mechanics, and numerous works have been done experimentally as well as theoretically. Although the central isentropic region bounded by the barrel shock wave and the Mach disk has been clarified, it is still not possible to evaluate the detailed structures of the freejets. Present paper aims to offer fundamental information of the supersonic freejets, with an emphasis to give data with which the shape of the freejets can be depicted under a specified condition. The TVD finite-difference scheme is adopted for the numerical calculation of the Euler's equations. The distributions of the flow properties are obtained for the three-dimensional axisymmetric and the two-dimensional freejets. The data are summarized to enable an estimation of the shape of the freelets.
