Experimental study of natural convection in thin horizontal liquid layers
experimentalstud00yurt.pdf (4.353Mb)Abstract
Heat transfer through a very thin horizontal liquid
layer bounded on top by a cooled glass plate and on bottom
by a heated copper plate was measured. Results were
correlated in terms of Nusselt number as a function of
Rayleigh number. Three different liquids were used under
conditions to give a range of Rayleigh number from 350 to
4100 and Prandtl number from 34 to 477. Up to a critical condition heat is transferred by
conduction alone. Convection appears when Ra = 1600 ± 100.
A correlation for critical Rayleigh number as a function of
Prandtl number was obtained.
