摘要：
The entrance region flow of Herschel-Bulkley fluids in a duct has been investigated numerically without pre-assuming the form of velocity profile within the boundary layer region which is determined by a cross-sectional integration of the momentum differential equation for a given distance from the duct entrance. Using the macroscopic mass and momentum balance equations, the thickness of the core, the entrance length, the plug core velocity and the pressure drop have been obtained at each cross section of the entrance region of the duct for specific values of yield number and flow behavior index. © 1990.
