Validations for practical use of MPFI method

Abstract

Recently MPFI(Moving Particle Full-Implicit) is advocated as an analytic method for the high viscous fluid flow with the free surface. But there are still few quantitative evaluations about its utility. I expanded MPFI method into 3D and wall boundary model without using wall particles. I held simple validation cases of the hydrostatic pressure and the Hagen-Poiseuille flow, and also held cases of liquid rope coil to check the conservation of angular momentum and got satisfactory results.
