Popis: The enhancements that have recently been implemented into the URANUS nonequilibrium Navier ‐Stokes code in order to further improve the gas-phase modeling and the gas-surface interaction modeling are summarized. Validation of the improved code was performed against various free-e ight experiments such as BSUV II, MIRKA, FIRE II, Stardust, the air nozzle e ow experiment of Sharma/Gilmore, and the DLR body-e ap experiment. The e ightexperimentshavebeenpartially recomputedto demonstratetheine uenceoftheenhancements. Theine uence of the enhanced modeling on postshock, boundary layer and wake e ow and aerothermal loads are discussed in detailforlowtohighreentryvelocities.Todemonstratetheimprovedmodelingandcredibilityoftheenhancedcode, measured aerothermal loads were recomputed along the e ight trajectories for a wide gas state and velocity range.
