## Abstract Twoβphase, annular flow of gases and nonβNewtonian liquids through horizontal pipes is modeled, and a prediction method for pressure drop and gas volume fraction is proposed. The prediction method consists of a modification, based upon shear rate dependence of the apparent viscosity of
The plane Couette flow of a frictionally heated temperature dependent Ellis fluid is solved. The critical stress, above which steady-state temperature and velocity fields under prescribed boundary conditions cannot be established, is determined as a function of the Ellis number El and the parameter
