采用试验与数值计算相结合方法研究了不同旋流器型式对双旋流式空气雾化喷嘴喷雾特性的影响规律。采用粒子图像测速(PIV)测量了不同空气雾化喷嘴下游流场结构,并且采用高速摄影仪和激光粒度分析仪,对不同空气流量和燃油流量下的双级旋流空气雾化喷嘴的油雾场形态、索太尔平均直径(SMD)、Rosin‑Rammler分布进行试验研究;同时采用数值计算方法获得了带双级轴向旋流器的空气雾化喷嘴二次雾化特性。结果表明:相同的工况条件下,带双级轴向旋流器的空气雾化喷嘴雾化锥角会稍大于径向旋流器。带双级径向旋流器的空气雾化喷嘴主要依靠离心喷嘴本身进行雾化,空气雾化效果有限,而带双级轴向旋流器的空气雾化喷嘴在进出口总压损失较小时离心喷嘴本身的一次雾化占主导地位,在总压损失增大后气动雾化效果逐渐起主要作用。数值计算结果与试验结果符合较好,表明该数值计算方法可用于空气雾化喷嘴雾化过程数值模拟,并且利用数值计算结果解释了燃油二次雾化过程。
The influences of different swirler types on the spray characteristics of dual⁃stage swirl airblast atomizer were investigated by using a combination method with experiment and numerical calculation.Particle image velocimetry (PIV) was applied to measure the downstream flow field structures of different swirler types,a high⁃speed camera and a laser particle size analyzer were used to photograph the atomization morphology,measure Sauter mean diameter (SMD) and Rosin⁃Rammler distribution under different air flow and fuel flow rates.At the same time,the secondary atomization characteristics of the dual⁃axial swirl cup were obtained by using the numerical calculation method.The results showed that,under the same working conditions,the atomization cone angle of the atomizer with two⁃stage axial swirler was slightly larger than that of the radial swirler.The atomization process with dual⁃stage radial swirler mainly relied on its centrifugal atomization of the atomizer,and the air assisted atomization was limited.The atomization process with dual⁃stage axial swirler was mainly affected by the first atomization of the atomizer when the pressure loss of swirl cup was small.With the increase of pressure loss,the air assisted atomization effect gradually played a major role.The numerical calculation results were in good agreement with the experimental results,indicating that the numerical calculation method can be used to simulate the atomization process of the dual⁃stage swirl airblast atomizer,and the numerical results can be used to explain the secondary atomization process.
