Estimation of swirl intensity behind short twisting devices

The numerical results of the effect of short twisting devices on the damping coefficient of swirl are presented. As for twisting devices four-, six- and eight-blade inserts with a twist ratio S/D = 3...5. To describe the rheological behavior of a pseudo-plastic fluid, the 0.65% aqueous carboximethyl...

Description
Summary:The numerical results of the effect of short twisting devices on the damping coefficient of swirl are presented. As for twisting devices four-, six- and eight-blade inserts with a twist ratio S/D = 3...5. To describe the rheological behavior of a pseudo-plastic fluid, the 0.65% aqueous carboximethyl cellulose (0.65% CMC) solutions is taken. The problem is solved by using Comsol Multiphysics.
