Kurzfassung
The interaction of NO- and N2-molecules of high kinetic energy colliding with a solid wall is investigated by laser induced fluorescence (LIF) and electron beam fluorescence (EBF). These two spectroscopic methods give complete information on the population of the rotational levels of the molecules. Using pure test gases N2 or NO or NO/N2 mixtures provides flow velocities from 800 to 1500 m/s in a supersonic free jet expansion; seeding with light gas like. He accelerates the flowing molecules up to 3000 m/s. The experimental results show a strong influence of the kinetic energy of the incoming flow, a minor influence of the wall temperature, a minor influence of the wall materials (except NO on Pt and NO on tungsten), and an influence of the Knudsen number except for the free molecular conditions
