A PIONEERING ERA IN CONVECTIVE HEAT TRANSFER RESEARCH
E. R. G. Eckert
Convective heat transfer research had a pioneering
era in the years between 1900 and 1930.
Wilhelm Nusselt demonstrated by similarity analysis
that a dimensionless parameter describing heat
transfer [the Nusselt number] can be expressed as a
function of Reynolds and Prandtl numbers for forced
flow of a constant property fluid and as a function
of Grashof and Prandtl numbers for natural convection.
This created the possibility to correlate
and generalize experimental results. Ernst Schmidt
formulated the heat-mass transfer analogy, again
for a constant property situation, which allows one to
obtain relations for mass transfer processes from
equations describing analogous heat transfer situations
without any additional experiments.
