The Effect of Variable Properties on Momentum and Heat Transfer in a Tube with Constant Wall Temperature
Herwig, H. Voigt, M. Bauhaus, F.-J.
The Effect of Variable Properties on Momentum and Heat Transfer in a Tube with Constant Wall Temperature - 1907-1915 p.
The effect of variable properties on momentum and heat transfer is investigated applying an asymptotic method that had been used before with the thermal boundary condition qw = const. Though the changes are in the thermal boundary condition only it turns out that both cases are quite different in several aspects. As a main result it turns out that a method empirically used in both cases (property ratio method) is not uniquely valid in the Tw = const. case of this study.
