Velocity Distribution for the Flow of the Second-order Fluid with Variable Coefficients in Concentric Annulus with Isometric Ring Slots on the Inner Cylinder

Abstract:

The governing equations of flow of the second-order fluid with variable coefficients through 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 influence of slot width, slot depth, slot interval and slot number on velocity distribution is analyzed. The results show that slot width and slot depth is related with radial velocity, axial velocity and resultant velocity, slot interval is related with radial velocity, which is little related with axial velocity and resultant velocity, slot number is little related with radial velocity, axial velocity and resultant velocity.
