Scientific paper

This work is a combined experimental and numerical study to assess the effect of nonequilibrium flow on the shock layer radiation surrounding the Huygens probe which will enter the atmosphere of the Saturnian Moon Titan at a speed somewhat under 6 km/sec in the year 2003. The radiation is especially enhanced due to the presence of a few per cent of methane along with the preponderance of nitrogen. The laboratory experiment measured the radiation behind a hypervelocity shock penetrating a simulated Titan atmosphere, while the numerical studies, making use of a three-temperature model, utilized a modification of Chul Park's NEQAIR code to obtain radiation intensities. Agreement with experiment was good and verified that the nonequilibrium flow behavior produces nearly an order-of-magnitude increase in the shock-layer radiation-to the extent that the radiative heat transfer to the surface becomes comparable to that due to convection.
