首先从理论上推导出在典型湍流边界层模式的非拟序结构下空泡与固体颗粒的近壁区运动方程，然后推导出湍流近壁拟序结构作用下的空泡与固体颗粒的近壁区运动方程，再将两种不同条件下的的运动方程进行比较，指出湍流近壁区的拟序结构对空蚀与磨损的发生具有决定性的意义，即正是由于拟序猝发作用的存在，才使得空泡、沙粒对壁面的空蚀与磨损作用得以发生。 | | 4. | Fluid machinery in these areas is damaged due to cavitation and sand abrasion , which has threaten directly the safety operation of hydraulic and hydroelectric engineering , causing huge economic losses . the research , therefore , on the combined effect of cavitation and sand abrasion is of great significance . the researchers at home and abroad have done a lot of work on this issue
我国许多河流的含沙量较大，如著名的黄河干流年均含沙量达37 . 9m ~ 3 / s ，黄河三门峡的年平均输沙量达16亿t ，这些地区使用的泵、水轮机等许多流体机械都在夹沙水流的作用下，受到了沙粒磨损与空化剥蚀的联合破坏，这种破坏直接危害了水利水电工程的安全运行，造成了巨大的经济损失，因而对含沙水流条件下空化剥蚀与泥沙磨损联合作用进行研究有着很大的工程实际意义。 | | 5. | Through comparison , it can be seen that the turbulent coherent structure near the wall influences directly the striking effect of the bubble and sand . a new proposal is put forward at the end of the thesis that the destruction caused by the combination of cavitation and sand abrasion can be mitigated by means of controlling the turbulent coherent structure near the wall
最后用有关的结论对过去的空蚀与泥沙磨损联合作用的一些试验观测结果进行了定性的分析、评述，并提出通过控制拟序结构的发生以达到控制空泡、沙粒对壁面的冲击作用是减轻磨蚀破坏的一条新的途径。 |
