Due to its complexity of the problem, the theories and experiment results obtained are discrepant, and some of them are even contrary one another. started from the influence by movement rules of small cavities and solid particles, the mechanisms of combined effect of cavitation and sand abrasion are study in this thesis from the aspect of the turbulent coherent structure near the wall. first, a dynamic equation is established for a single spherical bubble and single spherical sand under the non - turbulent coherent structure near the wall, and then a dynamic equation established under the turbulent coherent structure near the wall
首先從理論上推導出在典型湍流邊界層模式的非擬序結構下空泡與固體顆粒的近壁區運動方程，然後推導出湍流近壁擬序結構作用下的空泡與固體顆粒的近壁區運動方程，再將兩種不同條件下的的運動方程進行比較，指出湍流近壁區的擬序結構對空蝕與磨損的發生具有決定性的意義，即正是由於擬序猝發作用的存在，才使得空泡、沙粒對壁面的空蝕與磨損作用得以發生。 -
Based on the previous studies, the 2 - d laterally averaged temperature model for the temperature prediction of the huge and deep reservoir is developed in this paper. in the mean while, the movement mechanism of the turbulent buoyant flow in reservoir and the rule of the thermal stratification forming, developing and varying are probed. the model is then applied to the huge reservoir of xiluodu on jinshajiang river and the cascade power stations on yalongjiang river
本文在總結前人研究成果的基礎上，探討了水庫湍浮力流的運動機理，以及溫度分層的形成、發展和變化規律，建立了適用於大型深水庫水溫預測的立面二維水溫模型，並應用於超大型水庫? ?金沙江溪洛渡和雅礱江梯級電站各水庫的水溫預測，取得了一系列創新性研究成果。 -
In the next part, after verifying the simplified computational method of turbulence, the movement of fibers in turbulent pipe flow was simulated by 3 - d integral method and simplified computational method of turbulence. it was found that the fluctuation of turbulence caused random of fibers " orientation and its distribution became broader as the re numbers increased
然後，在驗證了湍流的簡化方法的合理性后，利用三維分段計算方法和湍流簡化方法模擬了大量纖維粒子在管道湍流內的運動，得出的結果為：湍流的脈動速度導致了纖維的偏角趨于無序，且隨著re數的增加，纖維偏角的分佈越來越趨于均勻。 -
Along with adult ' s joining, the movement project expands greatly, now had the rock climbing, the mountain glide, the turbulent current skin raft, the surfing, jump jump extremely, the slide ( skidding of the wheels, small wheeler ) u to jump on land and the aquatic sports project and so on match and block steeple race
隨著成人的加入，運動項目大大地擴展，現在已有攀巖、高山滑翔、激流皮劃艇、沖浪、蹦極跳、滑板（輪滑、小輪車）的u臺跳躍賽和街區障礙賽等陸上和水上運動項目。 -
The results show that rsm can accurately simulate the movement of the turbulent buoyant flow in reservoir and the anisotropic turbulence due to the thermal stratification. however, rsm is difficult in convergence, bad stability and more time consuming. rsm is suitable when the high accuracy is concerned and geometry boundary is simple
結果顯示， rsm模型能精確模擬水庫中湍浮力流運動規律和由於溫度分層引起的紊動量的各向異性的特徵，但其收斂性、穩定性及經濟性較差，適用於計算精度要求較高且流域邊界較為簡單的流動。
