The effect of fatty acid polarity on the combustion characteristics of vegetable oils droplets, CCO and CJO vegetable oil droplets have been studied experimentally with atmospheric pressure and room temperature. The role of intermolecular forces on the combustion characteristics of vegetable oils droplets. CCO and CJO are multicomponent vegetable oils, CCO represents saturated fatty acids while CJO represents monounsaturated fatty acids. The results showed that the burning rate of vegetable oil was influencing by the polarity of the fatty acids that compose it. CCO is dominated by polar fatty acids which shows a stable flame and around a flame shape. CJO which is dominated by non-polar fatty acids the results show an increase in the rate of combustion, the presence of microexplosion and the form of an elongated flame. The large CCO polarity causes the CCO to be more reactive, fast ignition of round and stable flame forms. The small CJO polarity causes the CJO molecules to be less reactive and slow to ignite. the shape of the flame on CJO extends upwards with microexplosion while in the CCO the way of the round flash. This is because of the different fatty acid content and geometry in each vegetable oils. © Published under licence by IOP Publishing Ltd.
