Abstract

Ice slurry is called a mixture of fine ice particles with a fluid carrier such as water. The PHASE CHANGE ability is reason for use of this mixture as the refrigerant cooling. In this research, flow of ICE SLURRY in horizontal tubes faring the PHASE CHANGE is numerically investigated using FLUENT software. The two-phase nature of ICE SLURRY mixture is studied using the Euler-Euler two-phase model based on kinetic theory of granular flows. The effect of ice particles PHASE CHANGE on HEAT AND MASS TRANSFER between phases are investigated, the obtained results show that the local heat transfer coefficient for the use of the icy slurry mixture is increased 12% compare to the pure water. It is also determined by examining HEAT AND MASS TRANSFER rate along tube, that the heat transfer coefficient for the pipe lengths larger than 10-15 times pipe diameter, remains constant. The variation of mean mass transfer is maximum at distance of 10-15 times of pipe diameter. The maximum value is 2-5 times larger than mean mass transfer in the pipe outlet. At the 20% end of the pipe, the decreasing trend of mass transfer accelerates.
