抄録

The incipient motion of a solid particle in water flows is experimentally and numerically investigated. The critical flow rate, in which an acrylic cylinder starts to move, was evaluated in a duct flow. Then, the flow field in the critical flow rate was measured by PTV and it was shown that the wake region is turbulent and that the intermittent vortex shedding occurs. The incipient motion of a particle was numerically predicted with MICS, which allows us to predict incompressible flows including multiple moving bodies and particles. As a result of computations, it was shown that the flow field and the initial movement of a particle are satisfactorily predicted.
