Abstract

Considering equipment damage, energy consumption enhancement and efficiency reduction during undesirable solidification pro-cess, this paper experimentally investigated the ability of clay nanoparticles to hinder the solidification procedure. The nanofluidswere prepared by dispersing various concentrations of clay nanoparticles (0.01 wt.%, 0.02 wt.% and 0.04 wt.%) in deionized waterwithout any dispersants. The solidification characteristics of nanofluids were determined by using cooling generator system. Theexperimental results of clay nanofluids showed a reduction in the nucleation temperature and an enhancement of supercooling degreeof about 25% during solidification process due to reduction in heat transport properties. According to the comparison results, it wasconstrued that providing supercooling condition, lower density nanoparticles are more able to advance in nucleation phenomenon andalso higher thermal conductivity nanoparticles have more tendency to reduce supercooling degree. Therefore, considering desirableand undesirable solidification, the best possible candidate of nanoparticles can be utilized based on their thermophysical properties.
