Influence of turbulence on mass transfer between a liquid and a solid sphere

Electrochemical measurements of overall mass transfer rates from a single sphere have been performed in a highly turbulent liquid. The increase in mass transfer rate due to turbulence has been shown to be more important at high Reynolds number and high turbulence intensity. Various equations of corr...

Description
Summary:Electrochemical measurements of overall mass transfer rates from a single sphere have been performed in a highly turbulent liquid. The increase in mass transfer rate due to turbulence has been shown to be more important at high Reynolds number and high turbulence intensity. Various equations of correlation have been proposed between the overall Sherwood number, the Reynolds number and turbulence intensity, the simplest one being \documentclass{article}\pagestyle{empty}\begin{document}$$ Sh = 6.82\,{\mathop{Re}\nolimits} ^{0.559}\, Tu^{0.069} $$\end{document} A correct agreement has been found with previous heat or mass transfer results between a gas and a sphere.
