Abstract

A numerical simulation of low Reynolds number nozzie flow was performed using the direct simulation Monte Carlo (DSMC) method. The Reynolds number regime studied was 100-1000. Two nozzle configurations investigated. The first case compared the results with experimental data measured by Penko for code verification. The second flow sirnulation was performed using the nozzle configuration which is currently being investigated experimentally with laser-induced fluorescence (LIF). LIF will be used to measure axial velocity profiles in the nozzle exit plane, and the measurements will be compared with the DSMC calculations. The experimental facility is in the final stages of qualification testing, and results will be presented in the near future. The DSMC method compared well with Penko’s experimental data everywhere except at the centerline, possibly due to the large ceil size and low number of samples recorded at that location. The DSMC results from the second nozzle configuration should correlate well with the experimental measurements.
