In this study, the Multiquadric Radial Basis Function (RBF-MQ) interpolation technique is applied for the data transfer between Lagrangian particles and Eulerian grids in solving the incompressible Navier-Stokes equations. Also, the argument on selecting the optimal shape parameter (for MQ kernel) is resolved in the current work as well by using the information of the surrounding nodes. In order to preserve the continuity constraint on the particle level, the divergence-free interpolation scheme is proposed to interpolate the velocity from grid to particle. For validation purpose, a series of flow cases are solved by using the current Moving Particle with Pressure Mesh (MPPM) method and good agreement has been found between the current and the benchmark solutions. Also, we found that the current method is more accurate than our previous MPPM method. � 2021 Final 2023-05-29T09:06:16Z 2023-05-29T09:06:16Z 2021 Article 10.1016/j.compfluid.2021.104993 2-s2.0-85106590051 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85106590051&doi=10.1016%2fj.compfluid.2021.104993&partnerID=40&md5=1c87407c905c05188ee26894e13c9868 https://irepository.uniten.edu.my/handle/123456789/26039 226 104993 Elsevier Ltd Scopus |
