Abstract
Free convection in liquid metals is of significant practical
interest to the crystal-growing community since the adverse effects
of convective instabilities in the melt
phase can be frozen into the solid product. Here, we present the results of a
combined numerical and experimental study of steady convective flows in a sample
of liquid gallium which is heated at one end and cooled at the other. Experimental
measurements of temperature distributions in the flow are compared with the standard
Hadley-cell solution and with the numerical results obtained from a two-dimensional
model. Excellent quantitative agreement is found between all three for low Grashof
numbers but a systematic divergence between the results is seen as this parameter is
increased.
