Mathematical modelling for carbon dioxide equivalent prediction of greenhouse gases emitted from a small scale turbojet engine

Abstract

In this paper, carbon dioxide equivalent of greenhouse gases emitted from a small scale turbojet engine is investigated for various engine loads. Within this context, emitted greenhouse gases are measured in accordance of relevant regulations. Obtained emissions data is evaluated with the aid of a novel mathematical model. Presented mathematical model is developed to predict carbon dioxide equivalent of greenhouse gases emitted from a small scale turbojet engine. At first, emissions data of the engine is used to find emission index based upon combustion equilibrium. Afterwards, a novel correlation among emission index and carbon dioxide equivalent is put forth depending on IPCC definition. With the aid of this novel mathematical model, it is also possible to determine carbon dioxide equivalent of greenhouse gases emitted by different types of aircraft engine. Developed mathematical model can be beneficial to who deal with emissions characteristics and environmental assessment of aircraft engines
