FUEL DISINTEGRATION IN GAS ATOMIZERS
Краткое описание
Gas atomization of a liquid jet is experimentally studied. The liquid jet enters a convergent-divergent gas nozzle through a central tube with an exit within the diffuser. Gas atomizers may be divided into two types in accordance with their applications: (i) for boiler burners with a central body behind the exit from the liquid delivery tube at relatively large ratios of liquid/gas mass flow rate; (ii) for combustion chambers of engines without a central body at relatively small values of the ratio of liquid/gas mass flow rate. Efficiency of the former type of gas atomizers is compared with that of the pressure-swirl atomizers traditionally employed for fuel disintegration in power-plants. Experimental data for the latter type of atomizers as compared with results of prior theoretical modeling demonstrate its applicability for estimation of the atomizer's geometry and operating conditions necessary for producing the finest possible mixture.
