Abstract

This paper describes the techniques adopted for visualization of Rayleigh-Benard convection during solidification of eutectic, hypo- and hyper-eutectic salt solutions. Neutrally buoyant hollow glass spheres were inducted in the body of the solidifying salt solution. The convection currents were captured by scattering of a laser beam by these beads. The apparatus has two components, namely: (i) measurement of interface/mushy region movement and temperature distribution and (ii) flow visualization with laser beam scattered by hollow glass spheres. The distinct nature of convection cells in the eutectic and hypo eutectic region is brought out.
