Generalized Flow in an Annular Gap of a Viscoplastic Liquid with Temperature Dependent Viscosity,
Abstract
Investigation is reported of the nonisothermal stationary flow of a viscoplastic liquid between two concentric cylinders. The outer cylinder rotates with constant angular velocity, and there is a pressure gradient acting in a tangential direction in the gap. The limiting shear stress is constant, and the temperature dependence of viscosity is described by a hyperbolic law. Various flow regimes are examined, and attention is given to the effects of heat exchange. Formulas are derived for the temperature and angular velocity profiles, and ranges of parameters corresponding to different flow regimes are delineated. (Author)
