An Analysis of Turbulent Free Convection Heat Transfer from a Vertical Surface

Abstract

In the analysis of the turbulent free convection two different solutions are obtained ; one has a fundamental assumption that the temperature and velocity distributions in the boundary layer respectively take similar figures along the flow, and the other has a fundamental assumption that the laminar sublayer takes a Reynolds number 160. The former corresponds to the transient turbulent boundary layer and the latter to the ordinary turbulent boundary layer. Then referring to the experimental results, the most appropriate dimensionless heat transfer coefficients are represented.
