| Abstract |
This study experimented to understand the effects of transporting ice slurry through elbow and inclined tube. And at this experiment it used propylene glycol-water solution and a diameter of about 2mm ice particle. The experiments were carried out under various conditions, with velocity of water solution at the entry ranging from 1.0 to 3.5m/s and elbows and inclined tubes of 4 kinds angle with 30°, 45°, 90° and 180°. The pressure drop between the tube entry and exit were measured. According to angle of bending, the highest pressure drop was measured at 30° elbow and the lowest pressure drop was measured at 90° elbow, and there are only a little differences of pressure drop between 45° elbow and 180° elbow. According to angle of inclined tube, the highest pressure drop was measured at 90° inclined tube and the pressure drop at 45°, 30°, 180° inclined tubes were lower successively. The lowest pressure drop in elbows and inclined tubes was measured at velocity of 2.0～2.5m/s and concentration of 10wt%. |
