Hydrodynamic analysis of the flow of a liquid with an exponential rheological equation in the cylindrical channel of an extruder screw

Equations are obtained for the angular velocity profile and flow rate in the case of integral and nonintegral exponents n when a non-Newtonian liquid with an exponential rheological equation moves between two rotating cylinders in the presence of a tangential pressure gradient.Branch Institute of Chemical Physics, AS USSR, Moscow.
