| Abstract |
Pressure drop were experimentally investigated for ice slurry flowing in the acrylic pipes with inner diameter of 24mm. Ice slurry was made from 6.5% ethylene glycol- water solution, and the pipes is consisted of horizontal, vertical(upward and downward) and 90° elbow pipe. The ice packing factor(IPF) and the flow rate of the experiments were varied from 0 to 30% and from 5 to 70kg/min respectively. The measured pressure drop in various pipe positions were compared with those for the solution flow(IPF＝0). The pressure drop was larger than that for solution flows as the IPF increased when the flow rate was low or very high. Sharp increases in pressure drop were observed for the cases when IPF is more than 20% in horizontal and vertical pipes, whereas the pressure drop increased with the IPF simultaneously in an elbow pipe. |
