Graph-Based Learning of Free Surface Dynamics in Generalized Newtonian Fluids using Smoothed Particle Hydrodynamics
Hyo-Jin Kim, Jaekwang Kim, Hyung-Jun Park
In this study, we propose a graph neural network (GNN) model for efficiently predicting the flow behavior of non-Newtonian fluids with free surface dynamics. The numerical analysis…

Comparative Analysis of Granular Material Flow: Discrete Element Method and Smoothed Particle Hydrodynamics Approaches
Jaekwang Kim, Hyo-Jin Kim, Hyung-Jun Park
We compare two widely used Lagrangian approaches for modeling granular materials: the Discrete Element Method (DEM) and Smoothed Particle Hydrodynamics (SPH). DEM models individual…

Segment-Based Wall Treatment Model for Heat Transfer Rate in Smoothed Particle Hydrodynamics
Hyung-Jun Park, Jaekwang Kim, Hyojin Kim
In this study, a smoothed particle hydrodynamics (SPH) model that applies a segment-based boundary treatment is used to simulate natural convection. In a natural convection simulat…
