Viscoelastic fluids are a common subclass of rheologically complex materials that are
encountered in diverse fields from biology to polymer processing. Often the flows of …

We analyse the pressure-driven flow of the Oldroyd-B fluid in slowly varying arbitrarily
shaped, narrow channels and present a theoretical framework for calculating the …

In this work, we present numerical solutions to the benchmark flow past a sphere problem
considering the rheology of semi-diluted and concentrated wormlike micellar viscoelastic …

The famous White–Metzner (WM) constitutive equation expresses a relatively simple
nonlinear viscoelastic fluid of polymer melts. However, such a differential stress model …

This paper analyzes the ability of different machine learning techniques, able to operate in
the low-data limit, for constructing the model linking material and process parameters with …

This work puts forward a modeling study contrasted against experimental, with focus on
abrupt circular contraction flow of two highly-elastic constant shear-viscosity Boger fluids, ie …

In this paper we employ the closed-form of the Adaptive Length Scale Model (ALS-C)[Ghosh
et al.,“A new model for dilute polymer solutions in flows with strong extensional …

A two-dimensional mathematical model for a steady viscoelastic laminar flow in a confusor
was developed under the condition of swirled flow imposed at the inlet. Low density …

Abstract The High Weissenberg Number Problem (HWNP), which is the ceiling posed by the
degree of non-linearity a numerical scheme can resolve in the approximation of the solution …
