Double diffusive velocity measurement during the solidification process using particle image velocimetry

摘要

This paper discusses the advanced technique, Particle Image Velocimetry (PIV), used to measure the velocity distribution of double diffusive convection of a binary mixture during the solidification process. The experiments were conducted usingammonium chloride solution in a rectangular enclosure. It was found that the double diffusive flow is stronger at the beginning of solidification and decays as solidification proceeds.
