解釋
細長體理論-
Approximate calculation of super - cavity profile based on slender - body theory
基於細長體理論的超空泡外形估算 -
On the slender body theory, this thesis simulated numerically the movement of hundreds of fibers in pipe flow, and finally, got the macro character of pipe flow of fiber suspensions
本文採用數值模擬的手段，從lagrange法出發，利用細長體理論研究了大量纖維粒子在管流內的運動，並得出管道懸浮流的一些宏觀特性。 -
Using 2 - d strip method and the high - speed slender body theory, the heaving motion responses in regular wave of ship with combined appendage are computed. the results are compared with the results of naked ship hull, and the anti - pitching effect of combined appendage is validated. a method of optimizing the seakeeping is provided from the aspect of the ship hull
因此本文針對船舶耐波性能的優化，提出了一種減縱搖組合附體，將半潛艏和艏鰭安裝在常規單體船上，初步闡述了半潛艏和艏鰭的水動力作用機理，並按照二維切片法和高速細長體理論計算了加裝組合附體后，船舶在規則波中的垂向穩態運動響應，與裸船體的結果進行了比較，驗證組合附體的減搖效果，從船體本身出發提供了?種優化船舶耐波性的方法； 3 -
In this thesis, the application of fiber suspension and its research history are reviewed as well as its current research situations. the thesis also demonstrates in details the slender - body theory that is widely used under low re number conditions
本論文闡述了纖維懸浮流的應用意義、研究歷史與研究現狀，對低雷諾數下廣泛應用的細長體理論的基本原理及其應用進行了詳細介紹。 -
Firstly, when the pipe flow was laminar, the movement of fibers was computed in the 2 - d force formulae that were deduced from the slender body theory and in 3 - d integral method. results revealed that angles between fibers " axis and the orientation of flow would concentrate gradually on a low number as the re numbers increased. that is, the axis of fibers would rotate toward the orientation of flow
首先，當管道內流動為層流時，分別利用從細長體理論出發得出的纖維二維受力公式和三維分段積分計算方法模擬了大量纖維在流場中的運動，然後在最終時刻統計了纖維的偏角分佈，並得出相同的結果：隨著re數的增加，纖維粒子的偏角逐漸集中於小角度，即纖維軸線方向越來越集中於流向，此結果與實驗吻合較好。
