WebNov 1, 2024 · A semi-implicit pressure projection scheme ( Chorin, 1968) is utilized here to solve the filtered conservation laws through a divergence-free variant of incompressible SPH ( Cummins and Rudman, 1999 ). Initially, the particles are advected to an intermediate position ( r f ∗) with the actual velocity of known time level. WebA new multi-stage three-dimensional transient computational model to simulate powder bed fusion (L-PBF) additive manufacturing (AM) processes is presented. The model uses the discrete element method (DEM) for powder flow simulation, an extended smoothed particle hydrodynamics (SPH) for melt pool dynamics and a semi-empirical microstructure …

WebThe predictor–corrector scheme, based on the decomposition of Chorin (Reference Chorin 1968), was introduced by Cummins & Rudman (Reference Cummins and Rudman 1999) to SPH. In a predictor step the curl-free part of the Navier–Stokes equations is solved using an explicit Euler time step.
