An-Vo, D.-A. and Mai-Duy, N. and Tran-Cong, T. (2010) Simulation of Newtonian-fluid flows with C2-continuous two-node integrated-RBF elements. Structural Longevity, 4 (1). pp. 39-45. ISSN 1944-611X

Abstract

In this paper, the C2-continuous control-volume method based on 2-node integrated radial basis function elements (IRBFEs) [CMES, vol.72, no.4, pp.299-334, 2011] are further developed for the simulation of incompressible viscous
flows in two dimensions. Emphasis is placed on (i) the 2-node IRBFE discretisation of the stream function-vorticity formulation on Cartesian grids; and (ii) the development of a high order upwind scheme based on 2-node IRBFEs for the case of simulating convection-dominant flows. High levels of accuracy and efficiency of the present method are demonstrated by solving the lid-driven cavity problem.
