| Abstract: | Experimental research and theoretical analysis are carried out on the low-pressure airblast nozzle. Sufficient information from the main influences of the low-pressure airblast nozzle on the atomizing performance is obtained. According to elemental of similarity and peculiarity of low-pressure airblast nozzle, the cold similarity moduli of a new type of nozzle are deduced. A regression analysis of the multi-variable non-linear function was carried on with large amount of the experimental data. Two expressions connecting drop size(SMD) with the main influence factors are presnted. Moreover, some important conclusions of spray characteristics of the nozzle are found during analysis and comparing the experimental datas. The expressions and conclusions are trustworthy and reliable. |
