A study of aircraft life efficiency and the interference between propeller slipstream and airfoil aerodynamic force;

螺旋桨滑流与机翼气动力干扰及飞机升力特性研究

Among the usual methods for calculating slipstream flow-field,it is seldom that the slipstream contraction which definitely existsbehind propeller has been accounted.

常见计算螺旋桨滑流流场方法中，很少计及桨叶面附近必然存在的尾涡收缩。

As compared to those in a single-sized particle system of an identical total solid holdup,the changes in the slip velocity of a dominant component are smaller than those of an accessory component,and not only are the sizes of the two particles approximately the same.

在稳定的流动状态下,实验考察了铅直管内粒径不同的两组分粒子群的滑流速度,并与每一组分单独存在时的值进行了对比。

The micro scaling effect and slip effect on th.

对微机电系统(MEMS)旋转机械微轴承,尤其是微型干摩擦、电磁和气体轴承的研究现状进行评述,介绍微型干摩擦轴承、微型电磁轴承及微型气体轴承的各种润滑特性,主要分析微型气体轴承的设计、加工制造及动力润滑特性问题,分别探讨微尺度效应和滑流效应对微型气体轴承润滑特性的影响,并对相关领域的研究进展进行展望。
