โฆ Synopsis
The problem of laminar Newtonian converging flow in a conical tube is investigated. The inlet velocity profile is assumed to be parabolic. The equation of motion is simplified by assuming that the cone angle is small and that the streamlines are only slightly curved. A finite difference solution is derived for the variation in velocity and pressure downstream from the inlet. The finite difference solution reduces properly to known analytical solutions in the limiting cases of low Reynolds number and high Reynolds number. The technique demonstrated here should be applicable to flow development from an arbitrary inlet velocity profile.

A criterion for stability of laminar flow of purely viscous non-Newtonian fluids is proposed and compared with the criterion of Ryan and Johnson, and Hanks. The proposed criterion is found to be in good agreement with the experimental findings given in the available literature. A generalized relatio
