文摘

Solidification of phase change materials is studied under convective cooling. Solidification time decreases with subcooling and external heat transfer coefficient. Solidification time reduces 30–50% with 1.57 vol% nanoadditives. The effect of nanoadditives is more pronounced with water cooling than in air. Model is developed to predict solidification time with different convective cooling.
