A corrected smoothed particle hydrodynamics method for solving transient viscoelastic fluid flows
TL;DR: In this paper, a corrected smoothed particle hydrodynamics (CSPH) method is proposed and extended to the numerical simulation of transient viscoelastic fluid flows due to that its approximation accuracy in solving the Navier-Stokes equations is higher than that of the smoothed Particle Hydroxynet (SPH), especially near the boundary of the domain.
