The generalised Blasius correlation for turbulent flow past flat plates

TL;DR

This paper derives a theoretical basis for the Blasius correlation in turbulent flat plate flow, showing coefficient dependence on Reynolds number and validating it against experimental data.

Contribution

It provides a theoretical derivation of the Blasius correlation, linking coefficients to Reynolds number and confirming the correlation with experimental data.

Findings

Coefficients depend on Reynolds number

Experimental data aligns with the derived correlation

Theoretical basis for empirical power law established

Abstract

This paper presents a theoretical derivation of the empirical Blasius power law correlation for the friction factor. The coefficients in this correlation are shown to be dependent on the Reynolds number. Published experimental data is well correlated.
