  exit edge
1.In the new blades, the fatigue crack initiates and propagates in the stable slip band in the (111) plane (stage I) restricted by one of the largest grains extending to the surface in the zone of the entry or exit edge or on the side of the vane.
      
This means that the negative i of the entry edge ei is counterbalanced by the positive j of the exit edge ej.
      
Then there always exists an exit edge ej in the same sector that is closer to v; see Figure 5.
      
The exit edge, which was therefore the leading edge of the SLAMS in the plasma frame, had a clear high frequency wave associated with it.
      
  trailing edge of a
The formation of a laminar wake in the flow behind a shock wave when the latter is shed from the trailing edge of a semi-infinite plate is investigated in this paper.
      
Flow in the neighborhood of the trailing edge of a plate in a transonic flow of viscous gas
      
An investigation is made into the influence of the Mach number and the viscosity on the flow in the neighborhood of the trailing edge of a plate.
      
Turbulent flow of a fluid in the neighborhood of the trailing edge of a plate at zero angle of attack
      
The laminar flow regime of an incompressible fluid at the trailing edge of a plate was studied by Stewartson and Messiter [1, 2] by means of the method of matched asymptotic expansions.

The investment required for low head hydraulic machine, especially for tubular turbine, is a large proportion to the total investment of a power station. Simplifing machine structure is significant. We proposed to change the movable guide vane to the fixed one. By using movable runner blade for flow rate control, experiment in hydraulic property is made, and good results were obtained. Detection of fluid field distribution for different kinds of guide vanes is carried out, providing data for turbine guide vanes...

A theoretical calculation method has been used to calculate the internal flow in the two-dimensional impeller of centrifugal pump at various flow-rates. Comparing the calculated results with measured ones, both were in good accordance. It is noteworth that the calculated departure of head is less than 5 per cent, and this shows that the calculating method is useful for predicting the pump performance. Using the surface singularity method and Kutta condition presented in reference 1 , the velocity distribution in accordance with experimental data at exit can be obtained although by inviscid calculation method, and the angular momentum of flow will be reduced in the outlet region owing to the thick periphery of blade.

本文计算了厚叶片离心泵二元叶轮在不同流量下的内部流场和扬程,并与实验结果进行了比较,两者符合得较好。特别是扬程的计算精度在5%以内,表明该方法为预测叶轮的性能提供了一种新的手段。 本文计算的结果还表明,采用文献1提出的表面奇点分布法及库塔条件,即使是势流计算也可能得到叶轮出口处压力面流速大于背面流速这一与实际相符的结果。同时,厚叶片出口边的存在还将导致液流流出叶轮后角动量的减小。

After investigating the concave exit edge of slurry pump impeller, the paper points out the possibility to improve the flow passage wear of slurry pumps in the hydrodynamics point of view.
