ENGINEERING PROPERTIES OF NON-NEWTONIAN FLUIDS
Abstract
Methods for predicting accurately the onset of turbulence and the pressure drop characteristics of ducted, turbulent non-Newtonian fluids were developed for the simplest class of non-Newtonian systems, viz., purely-viscous materials. Semiquantitative measurements have shown the suppression of turbulence possible in viscoelastic systems. Agitation of non-Newtonian systems in cylindrical tanks was studied; methods for the prediction of the power required for such agitation has been developed to substantially the same level as for Newtonian fluids. Application of the analogy between rates of heat or mass transfer and the rate of momentum transfer enabled the direct application of the studies of turbulence in purely-viscous systems to the prediction of heat transfer rates in these fluids under turbulent flow conditions. The general Eyring rate theory was extended to encompass diffusion in slurries and in non-Newtonian fluids. (Author)
