摘要：

Useful engineering design charts are presented which make the design of concentric annular ducts for transporting yield-pseudoplastic non-Newtonian fluids and slurries in laminar motion an easy matter. These charts were computed from theoretical solutions of the equations of motion for the concentric annular geometry using the Herschel-Bulkley or yield-pseudoplastic rheological model. Practical examples are presented illustrating the use of the charts to compute volume throughput given pressure drop and also to compute pressure drop given volume throughput for a slurry of known rheological properties in a given concentric annulus. The design charts make such computations very simple to perform. Complete mathematical results from which the design charts were derived are also given. Thus, computations may easily be made for specific systems. © 1979, American Chemical Society. All rights reserved.
