| Abstract |
In this study, the flow characteristics around the cutter head, which makes the dredging soil suspended, were measured to evaluate the environmental affect of the dredging works. The PIV was used for measuring the flow characteristics around the cutter head for suction and non-suction cases. As the results, the mean velocity was decreased from the cutter head to outward. The mean velocity decreasing rate of the non-suction case was larger than that of the suction case, but the turbulence intensity decreasing rate of the non-suction case was smaller than that of the suction case because of the suction energy which makes the z-direction flow. |
