In this article manages the issue of stable electrically lead laminar progression of a gooey incompressible liquid stream associating two parallel permeable plates of a divert in the event of a transverse attractive field through base infusion and top suction. Dependable vertical stream is made and controlled by a weight slope. Vertical speed is enduring everywhere in the field stream. It implies v=vw=constant. Answer for little and huge Reynolds number is talk about and the diagram of speed profile for stream including parallel permeable plate with base infusion and top suction through a rakish speed Ω has been considered

Some experimental results on incompressible viscous fluid flow in the gap between two concentric rotating spheres are discussed. The flow field in the spherical gap has been studied qualitatively by flow visualization (photographs) and quantitatively by measurements by the hot-wire technique. For a wide range of Reynolds numbers, the friction torque was measured for several gap widths and a relatively simple method of determining the torque theoretically is given. At higher Reynolds numbers instabilities appear. Their different behaviour for relatively small and large gap widths is demonstrated. For the larger gap widths, the different appearance of the Taylor–Görtler vortices, the reason for their generation, their regimes of existence as well as their influence on the friction torque are thoroughly treated. Detailed information is given on the new effect of the dependence of the wavelength of the vortices on the Reynolds number.

Slip Boundary

The unsteady rotational motion of a slip spherical particle with a nonuniform angular velocity in an incompressible viscous fluid flow is discussed. The technique of Laplace transform is used. The slip boundary condition is applied at the surface of the sphere. A general formula for the resultant torque acting on the surface of the sphere is deduced. Special fluid flows are considered and their results are represented graphically.
