Abstract
The combustion behaviour of paraffin-based hybrid rocket fuels in combination with gaseous oxygen (GOX) was investigated in the framework of this research. Tests were performed in a 2D slab burner configuration with windows on two sides at atmospheric conditions. High speed videos were recorded and analysed in detail by using an automated video evaluation routine. Two different decomposition techniques were applied to the scalar field of the flame luminosity. The results show that the combustion is dominated by wave-like structures and that the most excited frequencies and wavelengths characterizing the liquid melt layer depend on the fuel viscosity and geometry.
