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…
Numerical Modeling of n-Hexane Pyrolysis with an Optimized Kinetic Mechanism in a Hydrogen Plasma Reactor
Subin Choi, Chanmi Jung, Dae Hoon Lee +2
The physicochemical mechanisms underlying the pyrolysis of n-hexane in a high temperature Ar-H2 environment were investigated for plasma pyrolysis process. An optimal chemical kine…
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…
Fast Marching based Rendezvous Path Planning for a Team of Heterogeneous Vehicle
Jaekwang Kim, Hyung-Jun Park, Aditya Penumarti +1
This paper presents a formulation for deterministically calculating optimized paths for a multiagent system consisting of heterogeneous vehicles. The key idea is the calculation of…
