Kurzfassung
This paper describes an experimental study on heat-flux mitigation within high-enthalpy ionized-argon flows by application of an external magnetic-induction field. Two different axially symmetric test models containing water-cooled magnet coils have been investigated. The models have been made of a material with low thermal conductivity to visualize surface-temperature distribution.The latter has been measured by infrared thermography. Heat-flux rates have been derived from measured front- and rear-surface temperatures, taking into account temperature-dependent material characteristics and considering radiative-cooling exchange to the environment. Flowfield properties have been quantitatively characterized by laser-induced fluorescence, microwave interferometry, emission spectroscopy, electrostatic probes, and pitot probes. In addition, high-quality video recordings and photographs have been taken for shock-layer visualization. Remarkable measured surface-temperature reductions (16 and 44%) and derived heat-flux mitigations (46 and 85%) have been observed in the presence of an externally applied magnetic-induction field.
