Flow Field of Flow of Fluid through Separate Layer Injection Allocation of Concentric Annuli with Isometric Ring Slots on the Inner Cylinder

The governing equations of flow of the Newtonian fluid through separate layer injection allocation of concentric annuli with isometric ring slots on the inner cylinder under the cylindrical coordinate system were established. The governing equations were numerically solved by the finite difference method, the distribution of the stream function and velocity of the flow was obtained. The results show that the distribution of the stream function and velocity in ring slots is related with inlet pressure gradient and slot width, the distribution of the stream function and velocity in ring slots is little related with slot depth and slot pitch.
