TI - Flow Simulations by a Particle Method Using Logarithmic Weighting Function T2 - Structural Longevity PY - 2010 VL - 4 IS - 3 SN - 1944-6128 AB - The application of a particle method to incompressible viscous fluid flow problems is presented. The method is based on the MPS (Moving Particle Semi-implicit) scheme using logarithmic weighting function. Numerical results demonstrate the workability and the validity of the present approach through incompressible viscous fluid flow in a driven cavity and flow behavior in a liquid ring pump with rotating impeller blades.
