“…The broader flame front suggests a longer combustion duration and a more dispersed heat release pattern. This behaviour aligns with the characteristics of diesel combustion, where the ignition and combustion processes are influenced by factors such as fuel properties and air-fuel mixing [13,15]. In the case of hydrogen combustion, the contours of pathline intensity coloured by total temperature reveal a dynamic and well-defined swirling motion within the Air Swirl Burner.…”

This paper presents a comprehensive study on optimizing the design of a vane-type air swirl burner, along with a computational analysis comparing the combustion of diesel and hydrogen fuel within the same burner. For the combustion simulations, a coupled approach was employed involving a Lagrangian approach with the Discrete Phase Model to track the trajectories of fuel particles providing a comprehensive understanding of the particulate dynamics within the system. This research aimed to analyze hydrogen's potential as a sustainable energy carrier in comparison to its conventional counterparts such as diesel fuel. The results showed that the contours of hydrogen fuel revealed a well-defined and intense flame front whereas it was not the same in the case of diesel fuel which had a less intense flame front.
