Numerical Calculation of Gaseous Transport Properties from the Hulburt-Hirschfelder Potential with Applications to Planetary Entry Thermal Protection
Abstract
Transport properties of dilute monatomic gases have been evaluated by means of the Hulburt-Hirschfelder (H-H) potential, which contains nonadjustable parameters determined completely from spectroscopic data. The H-H potential is shown to encompass five distinct patterns of binary collision dynamics, some of which include double orbiting. Since the collision dynamics are more complicated than those of commonly used potentials like the Lennard-Jones, the numerical routines to evaluate Chapman-Enskog collision integrals have been extensively revised. For applications to thermal protection during entry into atmospheres of the outer planets, transport properties of monatomic carbon gas at a temperature of about 10,000 K have been evaluated.
