On the wall with curvature, we use a no-slip boundary condition for a rounded wall, which is based on the interpolation and extrapolation techniques by using the velocities at near-wall lattice points. In order to examine the validity and accuracy of the method, tangential annular flow in gap between two coaxial cylinders is calculated, and the error analysis is performed for various lattice resolutions. Using this method, twophase flows containing a particle in a U-curved square pipe are simulated. The results show that the particle released from various initial positions laterally migrates toward an equilibrium position between the centerline of the pipe and the inner or outer wall. Also, the particle released from the same initial position migrates to respective equilibrium positions according to Reynolds numbers., Article, 計算数理工学論文集. 13:97-102 (2013)}, pages = {97--102}, title = {U字曲がり管内を流れる単一粒子の挙動解析}, volume = {13}, year = {2013} }
