Inertial migration of neutrally buoyant particles in a square duct has been investigated by numerical simulation in the range of Reynolds numbers from 100 to 1000. Particles migrate to one of a small number of equilibrium positions in the cross-sectional plane, located near a corner or at the center of an edge. In dilute suspensions, trains of particles are(More)
The robotic high-rise building maintenance system is an automated system of performing maintenance works on the outer walls of high-rise buildings, including cleaning, coating, and inspection. This study, a robotic high-rise building maintenance system is proposed that overcomes the conventional limitations and introduces an algorithm for contamination(More)
We have investigated the hydrodynamic drag force between charged particles in electrolyte solutions, specifically the electroviscous force that arises from the distortion of the electrical double layers by the flow field. We report an improvement on the thin-double-layer theory (S.G. Bike, D.C. Prieve, J. Colloid Interface Sci. 136 (1990) 95-112), using a(More)
