    摘要:

    采用試驗(yàn)與計(jì)算機(jī)模擬相結(jié)合方法，研究了圓盤(pán)霧化器最佳工作轉(zhuǎn)速,，不同轉(zhuǎn)速下圓盤(pán)霧化器的氣流速度場(chǎng),，并進(jìn)行試驗(yàn)驗(yàn)證,。結(jié)果顯示,，圓盤(pán)霧化器在選定的葉輪下，最佳工作轉(zhuǎn)速為1400 r/min,；圓盤(pán)霧化器氣流速度場(chǎng)基本呈軸對(duì)稱(chēng)形狀,，氣流速度以一定的擴(kuò)散角在中心平面內(nèi)擴(kuò)散，而且氣流速度沿中心線逐步衰減,；模擬值與試驗(yàn)值相關(guān)性較好,。

    Abstract:

    In order to investigate the characteristic of properties of the disc atomizer, the experimental and computational simulation methods were adopted. The optimum working rotational speed and the air velocity field at different rotational speeds of the disc atomizer were studied and validated by the experiment data. The results showed that the optimum rotational speed was 1400r/min at the selected impeller. The velocity field of the disc atomizer was axial symmetry. The velocity of central plane diffused at a fixed angle and decayed along the centre line. The simulation data was closely related to the experiment data.
