Abstract

We present results of a combined experimental - computational study of free jet flow produced by a 1 mm (height) × 5 mm (span) nominally Mach 2 supersonic jet. Twodimensional maps of ux, the component of velocity parallel to the principal flow axis, are obtained experimentally, by acetone Molecular Tagging Velocimetry, and computationally, by the Direct Simulation Monte Carlo method, at a stagnation pressure and temperature of ten torr and 300 K, respectively. In all cases, direct comparison of the experimental data and the predictions from DSMC showed excellent agreement, with only minor deviations which, in most cases, can be ascribed to either the inherent uncertainty in the MTV or small uncertainties in the measured wall pressures.
