Here we theoretically show consistent analytical expressions for the constant and convective heat transfer coefficients for various flows to make Newton's cooling law a complete scientific law. For this purpose, a three-dimensional (3D) energy transfer theory of thermal convection is developed, and ...

From these data, free convection heat transfer coefficients on the outside of the tube were calculated as a function of the Rayleigh number. A correlation of the form Nu = C1(Ra)C2 was then determined by a least-squares fit of the data.doi:10.1080/01457638008939569...
