HEAT TRANSFER CHARACTERISTICS OF FORCED CONVECTION FLOW OF SLURRY ICE INSIDE HORIZONTAL PIPE

摘要

This study concerns development of a heat transportation system using slurry ice that contributes to district heating/cooling system. The heat density of transportation using slurry ice is larger than that of cold water by 3.3 times. The heat transfer and pressure drop characteristics of forced convection flow of slurry ice that contains ice particles with 0.5-1 mm diameter was experimentally presented in this paper. The heat transfer coefficients agreed with Dittus-Boelter's equation. The pressure drop agreed with Blasius* equation at high velocity and at low IPF of slurry ice. The increase in the pressure drop of slurry ice however rose with decreasing velocity and decreasing IPF.
