| Research Abstract |
It is known that ice growth rate formed on cold surface decreases with ice growth because of thermal resistance of ice itself. A carbon nano-fiber (CNF), whose thermal conductivity is high, is used to improve the thermal resistance. Ice formation characteristics of CNF mixed water have been examined. On the other hand, when CNF mixed ice melts, convection heat transfer is dominant. Then, viscosity of CNF mixed water is different from that of pure water. So, melting characteristics of CNF mixed water has been examined. As a result, it has been found that an optimum value of CNF concentration exists for an ice storage system.
