Indeed, aircraft accidents leading to fires are often fatal and cause a lot of losses<br>both human and material. Moreover, in the context of reducing manufacturing costs and the use of<br>aircraft, they are still subject to optimization in energy performance. For this, the composite materials<br>used in their design are the subject of research and development. Composite materials have good<br>mechanical properties but have drawbacks when subjected to fire. In this scope, before being used in<br>aircraft design, composite materials are subjected to certification tests for fire resistance based on the<br>standard ISO 2685. These tests are carried out using the FAA standard NexGen burner. In addition, so<br>that the fire test meets the criteria of the standard ISO 2685, the flame must have a temperature of<br>1100 \u00b0C \u00b180 \u00b0C and a heat flux of 116 kW \/ m2 \u00b110 kW \/ m2<br>. In this context, the air \/ kerosene mixture<br>must be made in the right proportions with good conditions of temperature and pressure. In this study,<br>the equivalence ratio is calculated from the mixture between air and kerosene. The objective of this work<br>is to highlight experimentally and numerically the effect of the equivalence ratio on the dynamics of the<br>air \/ kerosene flame used for the standard tests. The numerical calculations have been carried out using<br>the CFD, FDS code and experiments carried out with the NexGen burner. A validation study showed a<br>good agreement between numerical and experimental results and highlights the capability of FDS to<br>simulate the reactive flows of an air \/ kerosene diffusion flame. Subsequently, from the numerical and<br>experimental results, it is shown that the flame meets the criteria of ISO 2685 for an equivalence ratio<br>about 0.79.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-297.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-297.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>R.
