| Popis: | Extended model is a theoretical and analytical model for evaporation ofhydrocarbon fuel droplet. This model assumes that there is a moving hydrocarbon fuel droplet in quasisteady environmental air. Four types of fuel (n-heptane, nhexane, n-decan, and light Diesel) are used for analysis at atmospheric pressure and temperatures from about (300 – 1500) K. The initial droplet size used is 100 μm for a Reynolds number ranging from (0.1 – 1800). Computer programs have been developed in (Matlab-7) language to find out the mass evaporation rate, variationof size, droplet life time, and flame stand off ratio. The percentage value for maximum mass evaporation rate from the extended model is (0.13%) greater than that obtained from the mass evaporation rate from classical model due to the increasing of the heat gain to the movement drop. the results are compared with the existing theoretical and experimental work in literature and acceptable agreements are obtained |
