Ultrasonic has being attracted much attention gradually in fuel atomization because of some specialities of cavitation and infection on liquid flow . in the course of atomization of pitchy oil , especially , does it show greatly its advantage , but its material atomizational mechanism need research ulteriorly . the primary content of this thesis is about adding cantilever reed to effervescent atomizer so as to combine ultrasonic and effervescent . this thesis has discussed ultrasonic some mechanism , ultrasonic dynamical procreator , effervescent and liquid mucosity infection on atomization , at the some time we make some experiments and discuss atomization rule following some machinery parameter and run parameter so as to find some rule about ultrasonic atomization and to rich the research of ultrasonic atomization mechanism . all that will be beneficial to the design about ultrasonic atomization atomizer 超聲波由于其空化機理及對液體的流變性影響等特性,在燃油霧化燃燒中逐步引起人們的重視,尤其在重渣油等高粘度液體的霧化過程中逐步顯示出其優越性,但其具體的霧化機理還需要做進一步的研究在氣泡霧化噴嘴基礎加入懸臂式簧片哨,將超聲波與氣泡霧化相結合是本文討論的主要內容本文從研究超聲波的一些機理入手,討論了超聲動力發生器氣泡霧化以及液體粘度對霧化質量的影響,并通過具體的實驗,根據實驗數據來討論霧化質量隨各種結構參數運行參數的變化規律,以便找到超聲霧化的一些規律,豐富對超聲霧化機理的研究,對超聲霧化噴嘴的設計具有一定的指導意義。 |

The windows stood wide open in the heat; the garden lay in thick, soft shadow, where the pitchy shapes of trees could be discerned . 窗戶在酷熱的空氣中敞開著;花園躺在又濃黑又柔和的陰影里,依稀可以辨出黝黑的樹木形態。 |
