Excess pressure-drop estimation in contraction and expansion flows for constant viscosity, strain-hardening fluids
This article addresses the issue of reproducing quantitative pressure-drop predictions for constant shear-viscosity fluids in contraction and contraction/expansion flow geometries. Experimental observations on pressure-drop for severe strain-hardening Boger fluids reveal significant enhancement above Newtonian fluids in axisymmetric but not planar configurations. This discrepancy has eluded pre...
متن کاملAsymmetric flows of viscoelastic fluids in symmetric planar expansion geometries
The flow of viscoelastic liquids with constant shear viscosity through symmetric sudden expansions is studied by numerical means. The geometry considered is planar and the constitutive model follows the modified FENE-CR equation, valid for relative dilute solutions of polymeric fluids. For Newtonian liquids in a 1:3 expansion we predict the result that the flow becomes asymmetric for a Reynolds...
متن کاملNumerical Simulation of Contraction Flows for Boger Fluids using Finite Volume Methods
INTRODUCTION Simulation of constant-viscosity memory-fluids flows is undertaken, considering single-mode differential models and two different numerical schemes. Comparisons are performed against experimental observations, for pressure drop (∆P ) and vortex cell-size (X). We interpret such issues through increasing flow-rate for a given fluid. Tests have demonstrated that this is equivalent to ...
متن کاملMicro-Bubbly Flows in Rotating Pipe Sections with Abrupt Expansion and Contraction∗
An investigation was carried out for swirling flow in a rotating pipe with highly viscous fluid containing micro-bubbles experimentally and numerically. In the numerical analysis, bubble trajectory of each bubble was calculated using resultant numerical flow field solutions. From experimental results, with an aid of the numerical simulation, data were obtained for the location of a stagnation p...
