サンドコレクタの砂泥回収特性(吹出し口形状の影響) Characteristics of Sand Collector(Effects of Shape of Injection Nozzle)
In the case of collecting the granular particles out of the bottom of water, it is very difficult to collect them only by the suction force. In the previous papers, it had been clarified that the particles are collected more effectively and smoothly by mounting the injection port at the collecting mouth. In order to improve performance of unit, especially for the particles of which contacting force are very strong, the double injection nozzle is newly proposed and tested. The experiments were carried out and the fluidized region of particles bed was visualized. As a result, the concentration of collected particles by using the double injection nozzle is improved comparing with the single injection nozzle.
