Numerical study on fiber suspensions in non‐isothermal viscoelastic media

Abstract

Purpose

The purpose of this paper is to examine the macroscopic and microscopic fields of fiber suspensions in the non‐isothermal situations, also to examine the effect of fiber on this non‐isothermal system.

Design/methodology/approach

Control equations are coupled and simultaneously solved by collocated finite volume method on fully triangular meshes.

Findings

Temperature dependence and wall temperature have significant effect on both macroscopic and microscopic fields of fiber suspensions. Moreover, the influence of fiber on the non‐isothermal system is similar to that of the isothermal system.

Originality/value

This is the first time that the microstructures of both molecules and fibers are presented in the non‐isothermal condition and it is hoped that the results will provide more insight into the microscopics of complex flows.
