“…Several studies about Cooling Rate were realized (Okawa et al, 2001;Yoon et al, 2001;Chen and Lee, 1998;Lee et al, 1996;Debenedetti, 1996;Gilpin, 1977). In these papers the Cooling Rate is defined as:…”

“…The material selection was based on the property of the PCM used and the potential applications [11][12][13][14][15][16]. Yoon et al (2001) [17] studied the freezing properties of water in a circular cylinder kept horizontally. During the initial phase of freezing, an annular ice layer started growing on the surface of the cylinder at a higher rate.…”

In the present work, the freezing and melting characteristics of water seeded with chemically functionalized graphene nanoplatelets in a vertical cylindrical capsule were experimentally studied. The volume percentage of functionalized graphene nanoplatelets varied from 0.1% to 0.5% with an interval of 0.1%. The stability of the synthesized samples was measured using zeta potential analyzer. The thermal conductivity of the nanocomposite samples was experimentally measured using the transient hot wire method. A ~24% (maximum) increase in the thermal conductivity was observed for the 0.5% volume percentage in the liquid state, while a ~53% enhancement was observed in the solid state. The freezing and melting behavior of water dispersed with graphene nanoplatelets was assessed using a cylindrical stainless steel capsule in a constant temperature bath. The bath temperatures considered for studying the freezing characteristics were −6 °C and −10 °C, while to study the melting characteristics the bath temperature was set as 31 °C and 36 °C. The freezing and melting time decreased for all the test conditions when the volume percentage of GnP increased. The freezing rate was enhanced by ~43% and ~32% for the bath temperatures of −6 °C and −10 °C, respectively, at 0.5 vol % of graphene loading. The melting rate was enhanced by ~42% and ~63% for the bath temperatures of 31 °C and 36 °C, respectively, at 0.5 vol % of graphene loading.

“…They observed that the inlet coolant temperature seriously affected the onset of the phase change of water, the supercooling time of water and the total charging time. Yoon et al [17] experimentally studied the freezing mechanism of supercooled distilled water in a horizontal cylinder at different cooling rates by visualization, using the optical holographic real time interferometry technique. Milon and Braga [18] investigated the solidification process of a cold storage system using water as PCM, encapsulated in spherical geometry.…”
