LES study of the impact of fuel composition on a swirl spray flame approaching blow-off Both, Ambrus Mira Martínez, Daniel Lehmkuhl Barba, Oriol Universitat Politècnica de Catalunya. Doctorat en Ciència i Tecnologia Aeroespacials Àrees temàtiques de la UPC::Enginyeria de la telecomunicació Spray nozzles Combustion engineering Combustió The present paper focuses on the large eddy simulation (LES) of the n-heptane and n-dodecane flames of the Cambridge swirl flames data repository (Sidey et al., 2017). The applied tabulated chemistry spray combustion model reproduces well the key phenomena controlling flame dynamics. The distinct volatility of the fuels is identified as the source of main difference between the n-heptane and n-dodecane flames.
