“…Papers with an analysis of emissions data from flights for selected airspace are also presented (Pham et al , 2010). Many interesting works are found in literature that is related to the development of models which are based on variety of tools and methods used for calculations or predictions of emissions characteristic for aero-engine (Starik et al , 2014; Synylo and Duchêne, 2014; Şöhret et al , 2016; Vancassel et al , 2014).…”

Purpose The purpose of this paper is to present an assessment method of the toxicity emission evaluation during combustion in the miniature turbojet engine. Design/methodology/approach A small-scale turbojet engine was used for the research because measurements on real aircraft turbines are complex and expensive. The experiment was performed in accordance with innovative BAT – CELL Bio – Ambient Cell method which consists of determination of virtual toxic impact of the gas mixture on the living cells; it is therefore a direct method. The most significant innovation of this method is that, during the test, which consists of exposing the cells to the gas mixture, the cells are deprived of culture fluid. Findings The preliminary analysis shows that the method used here allows to determine the virtual impact of the gases on the human respiratory system and skin. It could be useful in defining the arduousness of an airport. The obtained results show that both of exhaust gases represent similar toxicity. Practical implications The new in vitro method allows to determine the virtual impact of the gases on the human respiratory system and skin. Significant potential for further research not only on the miniaturised engines, but also in the case of real objects, as this method does not have to be performed in a laboratory. Originality/value The work presents potential application of the innovatory method for exhaust gases toxicity evaluation in jet engines, which could be useful in defining the arduousness of an airport.

“…A CRN combustion modeling approach to predict NOx and CO emissions in lean premixed gas turbines based on the flow pattern and temperatures inspired by CFD addressed by [ [30], [31]]. CFD has been used as a base for chemical reactor analysis of combustion by [32] and [39]. Fichet et al [33], have used a reactor network model for predicting NOx emissions in gas turbines.…”

Computational modeling of the combustion systems not only depends on the flow field typology but also requires well considering the turbulence-reaction interactions. Complex combustion chambers can increase numerical costs dramatically. This paper addresses a novel CFD-based chemical reactor network (CFD-CRN) integrated approach to predict combustion byproducts with high accuracy. This methodology uses turbulence intensity as a determining factor to generate clusters of reactors. The CFD simulations were performed with fine grids using the GRI-Mech 2.11 methane-air combustion mechanism with 277 elementary reactions of 49 species. The GRI-Mech 3.0 including NO formation and reburn chemistry, with 53 species and 325 reactions, is used for the CRN analysis. Implementing the CFD-based CRN, the authors found that the rate of production of NOx from the prompt, thermal, and N2O pathways are calculated as 47.37%, 22.18%, 30.45%, and 40.24%, 29.13%, and 30.63% for the Sandia flames D and E, respectively. The computational fluid dynamics reports for those pathways are predicted as 50.39%, 19.78%, 29.83%, and about 43.58%, 28.45%, and 27.97% entire the Sandia flames D and E, in order. It is deduced that the application of the hybrid CFD-CRN in combustion systems is not only reliable for its high accuracy but also is noticeably efficient for fewer CPU requirements and numerical costs, especially in industrial combustion systems.
