TL;DR

This paper introduces a method to unify heat transfer data for Newtonian and power law fluids into a single curve, enhancing understanding of turbulence and fluid dynamics.

Contribution

It develops a technique to collapse experimental heat transfer data into a master curve and explores the theoretical basis of fluid analogies.

Findings

Unified heat transfer data for different fluids

Implications for turbulence visualization

Theoretical insights into fluid analogies

Abstract

This paper presents a technique that collapses existing experimental data of heat transfer in pipe flow of Newtonian and power law fluids into a single master curve. It also discusses the theoretical basis of heat, mass and momentum analogies and the implications of the present analysis to visualisations of turbulence.
