An Experimental Study on melting phenomena of PCM affected by Ultrasonic Vibration in a square cavity

밀폐용기내에서 초음파 진도에 따른 상변화물질의 용융현상 연구

Solid-liquid phase change (i.e. melting or solidification) occurs in a number of situations of practical interest. Some common examples include the melting of edible oil, metallurgical process such as casting and welding, and materials science applications such as crystal growth. Therefore, due to the practical importance of the subject, there have been a large number of experimental and numerical studies of problems involving phase change during the past few decades. Also, this study presented the effective way to enhance phase change heat transfer.
