Stuart W. Churchill

TL;DR: In this paper, a simple expression for the space-mean Nu (or Sh ) for all Ra and Pr (or Sc) in terms of the model of Churchill and Usagi was developed.

TL;DR: In this article, a simple empirical expression for the mean value of Nu over the cylinder for all Ra and all Pr is developed in terms of the model of Churchill and Usagi.

TL;DR: In this article, a single comprehensive equation is developed for the rate of heat and mass transfer from a circular cylinder in crossflow, covering a complete range of Pr (or Sc) and the entire range of Re for which data are available.

TL;DR: The expression Y = (1 + Zn)1/n where Y and Z are expressed in terms of the solutions for asymptotically large and small values of the independent variable is shown to be remarkably successful in correlating rates of transfer for processes which vary uniformly between these limiting cases as discussed by the authors.

TL;DR: In this paper, a correlating equation for assisting convection was developed by combining correlating equations for pure free and pure forced convection, based on laminar boundary-layer theory for an isothermal, vertical plate.
