Note (General): Direct Simulation Monte Carlo (DSMC) calculations of the rotational relaxation of nitrogen in an isothermal bath and through a normal shock wave are performed using Classical Trajectory Calculations (CTC) and an improved intermolecular potential in order to make a physically accurate database for the assessment and improvement of DSMC rotational relaxation models. The Statistical Inelastic Cross-Section (SICS) model is modified by taking the total scattering cross section as the Variable Soft Sphere (VSS) cross section and calibrated so that the rotational temperature relaxation in an isothermal bath compares reasonably with the CTC-DSMC data over an appropriate range of bath temperatures. The Modified SICS (MSICS) model is applied to the DSMC calculation of the rotational relaxation of nitrogen through a normal shock wave. Comparisons of the MSICS results with the CTC-DSMC data and experimental measurements indicate that the MSICS model improves the physical accuracy of the SICS model.
