The theoretical calculation and the model experimental result both have confirmed that the built - up stabilizing appendage is able to reduce pitching n heaving motions and especially bow acceleration considerably
理論計算和模型試驗結果均證明了組合減搖附體能夠減小船的縱搖運動、升沉運動，尤其是大幅度降低首部加速度。In this paper the flow field of falling film along the inner of vertical tube is simulated and it ' s the necessary base of the further research that includes characteristics of heat and mass transfer in the absorber under the fluctuant state. in this paper the ocean fisher ' s movement in the ocean is studied and the physical and the mathematical models of fisher are founded, then the expressions of the force caused by the movement are obtained. the expressions are combined with partial different equations of falling film under the static state, thus the mathematical model of the falling film under fluctuant state can be gained
本文首先研究了船舶在海洋中的運動，建立了船舶搖擺運動的簡化物理模型和數學模型，得到了運動附加力的表達式；並在此基礎上將吸收管的運動附加力表達式代入靜止狀態下液膜流動的數學模型中，即得到了搖擺狀態下液膜流動的數學模型；然後對液膜流動的數學模型進行了簡化，在假定了速度分佈的條件下，得出了液膜流動的積分方程，經過以上簡化就將求解三維問題轉化成為求解二維問題；將積分方程離散化後用數值計算的方法模擬了整個流場。In this paper the flow field of falling film along the inner of vertical tube is simulated and it ' s the necessary base of the further research that includes characteristics of heat and mass transfer in the absorber under the fluctuant state. in this paper the ocean fisher ' s movement in the ocean is studied and the physical and the mathematical models of fisher are founded, then the expressions of the force by the movement are obtained. the expressions are combined with partial different equations of falling film under the static state, thus the mathematical model of the falling film under fluctuant state can be gained
