What is Investigations on Cellularization Instability of 2-Ethylfuran about?

a b s t r a c t 2-ethylfuran (2 EF) has potential as a biofuel for combustion devices. To apply it efficiently in combustion devices, it is necessary to study the combustion characteristics such as the intrinsic flame instability of 2 EF. The intrinsic flame instabilities of 2 EF outwardly propagating spherical premixed flames were theoretically and experimentally studied at initial temperatures of 373, 403, and 433 K, pressures of 1, 2, and 4 bar, and equivalence ratios of 0.7e1.4. The flame topography at different stages of flame development was examined. When large cracks appeared on the flame front surface, resulting in small cracks and new cell generation, the flame became unstable. Linear stability theory was used to investigate the effects of hydrodynamic instability and thermal-diffusion instability on the flame. The critical stability curves were plotted, and the theoretical calculations were consistent with the experimental results. The results showed that the best fits for the theoretical and experimental results were n 1⁄4 2pPe/48 and n 1⁄4 2pPe/80, respectively. The critical radius and Peclet number are calculated and discussed. The critical Peclet number decreased as
