Flow of non-newtonian polymeric liquids in curved conducts of elliptic cross-section

摘要

An attempt is made to calculate pressure drops in the laminar and the turbulent flow of generalised, purely-viscous, non-Newtonian liquids in curved conducts of elliptic cross-section. Secton variant of the several-stage transformation method is proposed.New dimensionless equations describing both the non-Newtonian flow and its pseudo-Newtonian analogue have been found. The experimental data obtained by the author shows good agreement with theory.
