  1. At the same time, the intrapartical diffusion and liquid internal mass transfer can been enhanced by ultrasound field, owing to additional stirring, the increasing rate of intraparticle diffusion coefficient is enhanced, while that of the liquid film mass transfer coefficient is reduced under ultrasound field

    模型研究表明: freundlich ?兩相阻力模型計算得到濃度與實驗測定值非常吻合,超聲場能有效地強化浸取粒內擴散與液膜傳質,攪拌作用下超聲強化液膜擴散的的能力降低,強化粒內擴散的能力增強。
  2. To solve the mathematic equations, the method based on condensation degree was used. the distributions of temperature, concentration and mass flux on the film surface ; of temperature and concentration in the vapor ; of heat transfer coefficient in the vapor and in the liquid were obtained by applying the model in the flow field

    採用冷凝度的方法對該數學模型進行求解,得出了汽相的濃度分佈和溫度分佈,界面處濃度分佈、溫度分佈和傳質速率分佈,以及汽相和液相的傳熱系數分佈。
  3. Exerting the model of two mechanism heat transfer, the formulation for heat transfer coefficient of liquid film which in smooth tube and equipped with spring inserts is given in this paper. heat transfer coefficient is presented which not only has relation to reynolds number, temperature difference, liquid characteristic, but also is greatly influenced by structure parameter of the spring inserts. experiments indicate the heat transfer coefficient of tubes equipped with spring inserts is 25 % higher than smooth tube

    實驗表明,傳熱系數和液膜雷諾數、傳熱溫差、料液物性參數利彈簧插入物的結構參數有關,實驗條件下,安裝有彈簧插入物的豎管降膜蒸發液膜側的傳熱系數比光管的傳熱系數可高達25左右,但某些結構參數的彈簧插入物會造成傳熱的惡化。
