  plane flow
A steady plane flow of an anisotropically polarizable liquid in a channel with nonparallel walls was considered.
      
The basic rheological relations for the motion of viscoelastic media and a thixotropic viscoelastic medium in a constant longitudinal velocity gradient field were developed in [1] for the case of plane flow with a stagnation point.
      
The plane flow of a perfectly conducting gas subject to a perpendicular magnetic field is considered.
      
Many studies have been made of plane flow of an incompressible inviscid fluid past a cascade of profiles with arbitrary stagger angle β≠0.

  planar flow
A study has been made of the region of existence of the various solutions in planar flow, and it has been shown that the optimal profile in the presence of a length limitation may have a blunt end, which is a segment of a boundary extremum.
      
Moreover, if in linearization we take the coordinates in planar flow as independent variables, then the flow past concave and convex corners is described in exactly the same fashion.
      
The integral methods of boundary-layer theory are used to examine the interaction of a turbulent wake with the outer flow for the example of planar flow.
      
The results of solution of the self-similar problem of planar flow of gas through a porous medium in the case of a quadratic law of resistance [1] are generalized to the case of axisymmetric motion.
      
It was proved that the results for a planar flow could be generalized to the case of 3-D fiber direction vector.

In this paper, the full criterion for the separation of the incompressible planar flow is studied. A full criterion for the flow separation which is more general than that in [1] is given. It may be pointed out that the MRS criterion, zero vorticity criterion, the singularity criterion and the criterion in [2] are not full for the unsteady flow.

本文研究了不可压缩流体平面流动的分离判据问题。得到了比文献[1]更为普遍的分离的充分判据,即定理一。文中指出,MRS判据,零涡判据,奇点判据以及文献[2]的判据在非定常流动中均不是充分的。

The asymmetric deformation problem can be transformed into aplane flow one to which the complex function analysis will be available if acoordinate system is taken up properly,i.e. a plane flow problem is considered,in a generalized manner,as only related to two coordinate axes. Basd on such atreatment, an analysis is made for cylinder's upsetting, extrusion of round barsand wire drawing. The practical results show entirely in conformity withthose by different upper bond methods, providing that the shape of deforma-tion...

The asymmetric deformation problem can be transformed into aplane flow one to which the complex function analysis will be available if acoordinate system is taken up properly,i.e. a plane flow problem is considered,in a generalized manner,as only related to two coordinate axes. Basd on such atreatment, an analysis is made for cylinder's upsetting, extrusion of round barsand wire drawing. The practical results show entirely in conformity withthose by different upper bond methods, providing that the shape of deforma-tion zone taken on is the same. It is also proved theoretically that the complexfunction method is applicable to the analysis of other plastic forming problemsonly if a coordinate system is taken properly with the complex function select-ed appropriately.

对于轴对称变形问题,如果能取合适的坐标系就可变换成用复变函数法能够解析的平面流动问题,即将平面流动问题广义地理解为只与两个坐标有关的流动问题。基于这种处理方法,本文对圆柱体的镦粗和圆棒、线材的挤压、拉拔进行了解析。结果证明,在实践上与采用同样变形区形状的其它上界法解析的结果完全一致,在理论上证明了只要坐标选取适当、复变函数选取合适,就可利用复变函数法进行塑性加工问题的解析。
