| 7. | In the first part , turbulent motion in convection zone as source to generate alfven waves is studied following lighthill - stein theory , in which the turbulent source was described by nonlinear terms in mhd equations 就是将mhd方程中的非线性项通过fourier变换转化为湍动源项,并采用kolmogroff幂律谱来描述对流层的湍动谱。 |

| 9. | The threshold of autoregressive orders is obtained to identify the flow regimes of bubbling bed and turbulent bed . the accuracies of identification of bubbling bed and turbulent bed are 94 . 3 % and 80 . 0 % respectively . the arma models of the signals acquired from experiments are constructed 在此基础上,利用模型阶数进行流型的判别,初步实验结果表明,所采用流型辨识方法是有效的,气固流化床中鼓泡床和湍动床的辨识成功率分别为94 . 3和80 . 0 。 |
| 10. | By comparing the dry plate pressures drop and distributions of velocities simulated on single valve with those of double valves , it was found that there was intense turbulence in the flow fields around fixed - valve , there were eddy areas between valve side orifices and tray wall , there were eddies above the valves too , these led to the complex behaviors of gas perforating valve , these had a great effect on the gas - liquid mass transfer process . at the same time , in order to prevent the disadvantageous effect of gas between one valve with another on the gas - liquid mass transfer , it was very effective to change the fields of gas perforating valve by folding the edges of valve 通过对数值模拟得出的单阀和双阀塔板的干板压降及流场速度分布分析对比后发现,固定阀周围流场存在较强的湍动,阀侧孔与塔板壁面区域以及阀体的上方空间存在明显的涡流区,使气体穿阀后的行为变得复杂,并对气液传质过程产生重大影响;模拟结果表明,为防止和削弱固定阀间的对冲造成的“死区”对传质带来的不利影响,通过折边来改变气体的气路是非常有效的,模拟值与实验值基本得到吻合。 |
