Abstract:
Aircraft engines are a source of significant greenhouse gas emissions, in particular CO$_2$. Due to the tightening of emission standards, ways to reduce CO$_2$ emissions from aviation are being sought. One of the most promising ways to achieve this goal is the use of fuels from renewable sources, such as plant materials. To simulate the working process of combustion chambers of aircraft engines when burning biofuels and their mixtures with petroleum fuels, knowledge of the physicochemical properties of such fuels is required. This paper provides a review of existing methods for calculating the physicochemical properties of oxygen-containing biofuels, including esters, alcohols and ketones. The presented methods are validated on substances acting as bioadditives to aviation fuel and analyzed in terms of calculation accuracy and ease of use for studying the working process in combustion chambers.
