内容記述 | Efficient techniques for cleaning scale in a U-tube of a heat exchanger are desired. Blast cleaning test was carried out using a real size U-tube of 13.5mm in diameter,8m of straight tube length,and 0.3m in radius of curvature. A combination of plastic particles and glass beads was selected for the blasting media. Swirl motion was added to the blasting media flow. The plastic particle-air two-phase flow with swirl motion in the tube was visualized. The loading ranged from 3.7 to 5.3. The estimated Stokes number was 1700 for the plastic-air two-phase flow. It was observed that just downstream of the bend,flow particle clusters repeatedly each other alternatingly located on the upper and lower sides of the tube. In the repeated blast cleaning experiments,it was found that the same characterstic large-scale cleaning distribution occured along the tube. | |||||
