Analogies Between the Heat and the Momentum Transfer

Abstract

Heat exchangers, boilers, and many other devices are commonly calculated using the heat transfer coefficient. For several dozens of years, a search has been going on for simple ${\text{Nu}} = f\left( {\text{Re} ,\,\Pr } \right)$ relations that could be applied in practice to calculate the heat transfer coefficient α on the solid body surface as a function of the fluid velocity, temperature, and physical properties.
