One of the main advantages of liquid fuels when compared with their gaseous counterpart is their high energy density at ambient conditions, which make their usage favorable for transport or storage issues. Therefore, during the last decades, a lot of attention has been given to combustion devices fueled with liquids. However, recently, in the context of climate protection, the acceptance of combustion-based technologies has lessened. Nonetheless, it is nowadays already clear that the future energy supply cannot solely be based on renewable forms, as solar or wind energy. One prominent example is the aviation sector, which is expected to further grow in the next decades and which will rely on liquid fuels. It is therefore essential to improve the general knowledge of combustion in order to reduce emitted pollutants and at the same time to improve the efficiency of the combustion process. On the other hand, further research is required in order to establish fossil fuels alternatives, namely renewable fuels (for instance Ethanol) as valuable option.
