The main work in this paper includes three parts : the theory research on partially - cavitating and super - cavitating axisymmetric bodies, the numerical computations and experimental investigations on partially - cavitation and super - cavitation on axisymmetric bodies. after finishing the study of theory and experiment on the partially - cavitation and super - cavitation for axisymmetric body, i use the potential flow theory to build the mathematical model on the partially - cavitation and super - cavitation for axisymmetric body. many cavity wake models, such as pressure recovery close model, riabouchinsky model and re - entrant jet model, are studied seriously
本文在深入研究了回轉體局部空化與超空化理論及實驗結果的基礎上，基於勢流理論，建立了回轉體局部空泡和超空泡流場的基本數學模型，通過對kinnas和fine 、 uhlman以及jiedang和gertkuiper等人基於二維水翼提出的壓力恢復閉合模型、鏡像板模型和回射流模型等空泡尾流模型進行了逐一的研究分析，發現其中的壓力恢復閉合模型較適用於模擬回轉體空泡尾部流場，並選用此空泡尾流模型作為求解回轉體空化流場正問題與逆問題的數學模型的組成部分。The effects of the slipstream boundary are solved by the slipstream boundary condition met using the so - called vortex image method. based on these considerations, the change in the circulation around the wing is obtained, and the velocities induced by the original vortices and the imaged vortices at the wing are subsequently derived. the present research also gives an analytical expression of the drag change due to the slipstream interference
