      摘要:
      為了探究波紋通道倒角連接處對流動和傳熱性能的影響365英超体育投注,本文針對非對稱波紋通道中大波谷半徑(rl)位于來流側和去流側進行了數值模擬研究。比較了不同雷諾數下對稱型與非對稱型波紋通道壁表面平均及局部表面特征數的變化規律。結果表明:壁表面平均努塞爾數(Nu)與局部努塞爾數(Nux)皆隨雷諾數(Re)的增大而增大,且對稱型波紋通道壁面Nu的增長速率大于非對稱型波紋通道365英超体育投注365英超体育投注;壁表面平均摩擦系數(f)與局部摩擦系數(fx)皆隨Re的增大而減小365英超体育投注365英超体育投注,且非對稱型波紋通道f下降速度相比對稱型小。非對稱型通道的Nu略小于對稱型通道365英超体育投注,但f卻大幅度降低365英超体育投注。2種非對稱型比較時,大波谷半徑位于來流側時流速較小且渦旋范圍較小,溫度邊界層略厚,壓力梯度的轉換較小,湍動能整體較小。鑒于上述研究,在換熱器設計上建議選擇rl位于去流側通道以提高整體性能系數365英超体育投注。
