  1. In the present work, there are two methods to design the shrouded - propeller. one is based on the blade element and momentum theory, the other is based on the ufbng - line ( surface ) theory derived from circumfluence theory

    在實際工作中,的設計有兩種方法,一種是基於葉素理論與動量定理的工程方法;另一種是基於升力線(面)方法的環流理論方法。
  2. In the 1960 ' s, the circumfluence theory has been used to design the shroud - propeller, and it can be divided to two methods, one is that the profile of die shroud is provided, the other is that the pressure distribution of the shroud is provided.

    到六十年代,的環流理論就可用來計算這種推進器的設計問題。本文中使用的方法是:用圓環渦系和圓環源、匯系模擬,用線性理論計算;用一個變負載的鼓動盤模擬。
  3. In this thesis we have get the profile of the shroud, the shroud is simulated by circle source and sink series, and the propeller is simulated by a actuating disk

    在計算的相互影響時,只考慮表面任一點上誘導速度的平均值,即軸對稱。
  4. In the other hand, the shroud designed properly can decrease the noise of the propeller system. so it is used widely in ships, aircraft, and is developing all along

    正是由於它的這些顯著的優點,被廣泛的用於輪船、特種飛行器(如地效飛行器) 、潛艇等的推進系統中,而對它的研究也在不斷發展中。
  5. The former is used widely because it avoids complex calculations. the later is used more widely with the developing of the cfd, and it can get more detail data and higher precise result for the propeller design

    前者由於沒有復雜的運算,也具有一定的工程實用性而被廣泛應用,而後者隨著計算機的發展而逐步完善,可以的來分析和計算的性能。
