Heat transfer from a cylinder of finite length

The analogy of heat and mass transfer is used to investigate the mean heat transfer from a cylinder of finite length as a function of the relative cylinder length, h/d. It is shown that a noticeable increase in the intensity of heat transfer occurs for an h/d less than 4. The effect of the saddle-shaped velocity profile on heat transfer is analyzed. Results are presented in the form of empirical expressions taking into account the effect of the Reynolds number, the degree of turbulence, the relative cylinder length, and the velocity profile inhomogeneity.
