      摘要:
      為分析非同心型擠壓油膜阻尼器的空化流場特性,本文利用Mixture多相流模型365英超体育投注、Zwart-Gerber-Belamri(Z-G-B)空化模型與動網格技術,建立了其三維非定365英超体育投注?栈鲌鰯抵的P。計算了不同供油壓力條件下內環進動的不同時刻擠壓油膜阻尼器流場的壓力與氣相體積分數分布365英超体育投注,并得到了阻尼器外環3處監測位置的油膜壓力與氣相體積分數的瞬時變化。將數值模擬得到的油膜壓力與文獻中實驗測得的油膜壓力進行對比365英超体育投注,結果顯示兩者基本一致365英超体育投注,驗證了本文的數值模擬方法具有較好的準確性。分析表明:升高供油壓力會使得該阻尼器空化流場高壓區范圍增大并移向進油側,使得低壓區移向出油側并且氣相體積分數顯著地減小。
