| Popis: |
Two optical techniques were applied to study the injection of fuel into the intake of a supersonic combustion ramjet (or scramjet). Fuel was injected into a supersonic air test gas at an angle of 45 degrees to the wall, through round portholes located 100mm downstream from the leading edge of a 9 degree intake. Holographic Interferometry was used to observe density variations in the flow allowing the detection of the fuel stream and shock wave structures in the flow. Planar Laser Induced Fluorescence was used to view the three-dimensional nature of the flow. This method allows a thin plane in line with the fuel injector to be viewed rather than the integrated image provided by the interferometry. The structure of the fuel jet could be seen in greater detail. The combination of optical techniques gave significantly more experimental information than wall pressure measurements. |
