Abstract

Calculations of the flow characteristics of polymer liquids in various processes of chemical technology are carried out with the use of two types of nonlinear rheological equations: relaxation (a system of differential equations) and integral. Unlike the equations of the integral type, which require integration along the trajectory of motion of a liquid particle, relaxation equations contain only quantities for one moment in time. Therefore, the relaxation equations are more convenient for practical work and permit the numerical solution of problems in rheodynamics and heat transfer by the traditional finite-difference methods.
