| 4. | By using a finite volume method to solve the navier - stokes equations , two - dimensional vibrating cascade flow was computed 采用有限体(面)积法求解navier - stokes方程,完成了二维振动叶栅流动数值模拟。 |
| 5. | The numerical flutter analysis system was formed by the three - dimensional numerical simulation of the vibrating cascade flow combined with the structural dynamics analysis of vibrating blade 将振动叶栅三维流动数值模拟与振动叶片结构动力学分析相结合,建立了叶片颤振数值分析系统。 |
| 6. | There were some intensively nonlinear features in the vibrating cascade flow . the frequency of the separated vortex ' s propagation was not equal to the vibrating frequency of the blade 二维分析中发现振动叶栅非定常粘性流动具有较强的非线性特征,振动诱发的分离涡传播频率与叶片的振动频率不一致。 |
| 7. | High - resolution nnd scheme and fully implicit dual - time stepping method were adopted in the three - dimensional vibrating cascade flow calculation . thus , the correct simulation of the shock in transonic flow and the efficiency of calculation were both taken into consideration 在三维振动叶栅流动数值模拟中,采用高分辨率tvd类型的格式和全隐式双时间方法,保证了对流动的正确模拟,准确地捕捉了跨音流动中的激波,其计算效率非常高。 |
| 8. | Because the cascaded flow - thought delay time . daily power benefit has affected not only by previous day but by next day , daily power benefit is composed of " plant day " part and " effect day " part . based on the theory analysis , author developed a program what can well describes the cascaded reservoir short - term optimistic dispatch system model 由于梯级水流滞时的存在,日发电效益既受前日影响,也影响次日,为考虑水流滞后带来的影响,将日发电效益视为两部分组成: “计划日”部分和“影响日”部分。 |
