Theoretical Investigation of Nano Fluid Heat Transfer Enhancement Considering the Effects of Melting Point Depression

B. Kirubadurai, P. Selvan, V. Vijayakumar, K. Kanagaraja

Abstract :

Melting point depression is the phenomenon of reduction of the melting point of materials with reduction of its size. This phenomenon is very prominent in Nano scale materials, which melt at temperatures hundreds of degrees lower then bulk materials. Melting point depression is most evident in nanowire, nanotube and Nano particles, which all melt lower temperature than the bulk amount as same materials. Changes in melting point occur because Nano scale materials have a much large surface to volume ratio than bulk materials, drastically altering thermodynamics and thermal properties.
