A COMPARATIVE STUDY OF OpenFOAM AND DualSPHysics FOR NON-NEWTONIAN FLUID FLOW ANALYSIS

Abstract

 Emerging as a powerful computational fluid dynamics (CFD) tool in recent years, open-source software is receiving attractive attention. The trend to use open-source software is expected to be increasingly stronger since current open-source software has many features and qualities comparable to a commercial one. Despite the importance of verification of accuracy in basic benchmark problems, open-source software has a tendency to be applied without adequate prior review. OpenFOAM and DualSPHysics are open-source software with potential applications in ocean engineerings. In this study, we have compared OpenFOAM and DualSPHysics for non-Newtonian fluid analysis through the benchmark tests of the Poiseuille flow and slump test. We have demonstrated that both models are robust tools for the analysis of non-Newtonian fluid flows. The main practical contribution of this work is to reveal the advantages and disadvantages of each software, which cannot be seen by just applying each software, and to multifacetedly discuss the applicability of OpenFOAM and DualSPHysics in the marine development engineering.
