Newton's law of cooling states that the heat transfer rate leaving a surface at temperature Ts into a surrounding fluid at temperature Tf is given by the equation:Qconvection = h A (Ts - Tf)where the heat transfer coefficient h has the units of W/m 2 . K or Btu/s.in 2 .F. The...
The results show that there is a significant change in the angtilar variation of the internal heat transfer coefficient at low quality when compared with values for high quality. At low quality, the highest internal heat transfer coefficients are obtained on the tube surface farthest from the ...

The convective heat transfer coefficient distribution has been restored on aluminum plates coated with a hydrophobic oleic film on which the dropwise condensation of the water vapor carried by a humid air turbulent stream occurs. The refinement of the technique in relation to its ability of capturing...
