Abstract
The computations of a near-continuum flow with separation were performed using the DSMC method for a hollow cylinder flare and a double cone configurations. Different test cases were considered with the Reynolds number in the range of 12,000 to 26,000. An efficient spatial correlator is developed for the DSMC method to estimate an impact of the statistical dependence between molecules on simulation results. Very good agreement between the numerical results and available experimental data is obtained for the least dense case, where the DSMC requirements for cell size and the number of molecules are satisfied. For more dense cases, even 80 million molecules and 20 million cells do not satisfy the DSMC requirements, resulting in the underprediction of the separation zone size.
