文摘Slinger is a rotary atomizer whose atomization performance is affected by the parameters of orifice.8 kinds of orifices with different structure parameters were investigated,and an optimal diameter exists for the round orifice with that the spray SMD is the smallest and the uniformity is the best.Increases in the axial length of slot orifice decrease the spray SMD and improve the spray uniformity,but increases in the width of the slot orifice are invalid for liquid spray SMD,and the spray uniformity becomes even worse.In most cases,the spray SMD of slot orifice is smaller than that of round orifice with the same perimeter,and the spray uniformity is better likewise.Increases in radial length of orifice cause the spray SMD to be larger,but the spray uniformity become obviously better.The spray SMD become larger with decreases in liquid surface tension.The spray uniformity became better nevertheless.
