摘要

This paper reports the velocity distribution of double-diffusive convection of a binary mixture in a rectangular enclosure during the solidification process. The mixture was a NH_4Cl-H_2O solution. The advanced technique, particle image velocimetry (PIV), was usu0005d to measure the velocity distribution in the liquid region during solidification. For the purpose of comparison ,the solidification of pure water was studied with the same technique. The temperature of the cooling walls in the test chamber and the temperature of the test solution during solidification were also measured .The double-diffusive flow was found to be stronger at the bu0005ginning of solidification; the flow decays as solidification proceeds .The velocity distribution of the hypereutectic solution of NH_4Cl-H_2O has evident difference in comparison with hypoesutectic solution.
