Description
About the NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
Description:
Entry probes entering the Saturn atmosphere are subject to convective and radiative heating by Hydrogen atoms, molecules and ions formed in the shock layer gases. Radiative heating in H2 shockwaves is reproduced in the NASA Ames Electric Arc Shock Tube (EAST) facility, and is used to test models developed to predict the heating mechanisms. The primary models employed are the DPLR computational fluid dynamics code and the NEQAIR radiative solver. Comparisons of DPLR/NEQAIR results to EAST measurements reveal several discrepancies which may be addressed by improving model fidelity and input parameters such as rate and transport coefficients, state-to-state transition data and radiation transition moments. This post-doctoral position will examine higher fidelity approaches that address thermal and chemical non-equilibrium and non[1]Boltzmann kinetics that may impact the Hydrogen simulations. Modifications to calculation procedures in order to account for these higher fidelity approach will be merged into the CFD and radiative codes in a tractable manner that could be used for future studies of entry systems.
