  4. 3. Optical Analysis of the Hydrogen Cooling Film in High Pressure Combustion Chambers

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Fabian Weber; [2019]
    Keywords : optical; analysis; hydrogen; h2; cooling; film; high; pressure; combustion; chambers; rocket; engine; thrust; experimental; oh*; shadowgraphy; flame; emission; lox; liquid; bipropellant; cryogenic; efficiency; heat; flux;

    Abstract : For performance optimisation of modern liquid cryogenic bipropellant rocket combustion chambers, one component which plays an important role in reducing the wall side heat flux, is the behaviour of the cooling film. At the Institute of Space Propulsion of the German Aerospace Center (DLR) in Lampoldshausen, hot test runs have been performed using the experimental combustion chamber BKM, to investigate the wall side heat flux which is -- among other factors -- dependent on cooling film properties.

  5. 4. Ray Tracing and Spectral Modelling of Excited Hydroxyl Radiation from Cryogenic Flames in Rocket Combustion Chambers

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Jaka Perovšek; [2018]
    Keywords : spectral modelling; excited hydroxyl radiation; OH* radiation; ray tracing; spectroscopy; rocket combustion chambers; rocket engines; hydrogen-oxygen combustion; combustion instabilities;

    Abstract : A visualisation procedure was developed which predicts excited hydroxyl (OH*) radiation from the Computational Fluid Dynamics (CFD) solutions of cryogenic hydrogen-oxygen rocket flames. The model of backward ray tracing through inhomogeneous media with a continuously changing refractive index was implemented. READ MORE
