文摘

External pulsations are applied on a flame by cam operated piston device. Effect of pulsations on diffusion and partially premixed flames are studied. Transient flame images are analysed by digital signal processing. ‘Tip flickering’ is observed at low fuel flow rate. ‘Bulk flickering’ is observed at high fuel flow rate.
