Abstract
This paper reports computational analysis in support of experiments in a high enthalpy arcjet wind tunnel at NASA Ames Research Center. These experiments were conducted in the NASA Ames 60-MW Interaction Heating Facility and include surface temperature measurements of swept-wing leading edge shaped pylon models. Surface temperatures of the arcjet pylon models were measured with thermocouples, an infrared camera, and a pyrometer. During the facility characterization runs, surface pressure and heat flux measurements on a water-cooled calibration plate were obtained. The present analysis comprises computational simulations of the nonequilibrium flowfield in the facility (the nozzle and the test box) and comparisons with the experimental measurements. The value of computational fluid dynamics simulations in planning and analysis of a complex arcjet test configuration is demonstrated.
