Abstract

MD-DRM mass conservative interpolation for the solution of non-linear viscous flow problems W. F. Florez* & H. Power? ^Wessex Institute of Technology, UK on leave from Energy and Thermodynamics Group, UPB, Columbia ^Department of Mechanical Engineering, The University of Nottingham, UK Abstract In this paper we introduce a radial basis function interpolation scheme for the velocity field, that satisfies the continuity equation (mass conservative). The proposed method performs better than the classical interpolation used in the DRM approach to represent such field. The new scheme together with a subdomain variation of the dual reciprocity method allows better approximation of the nonlinear terms in the Navier-Stokes equations. 1 Introduction The aim of the present work is to show how DRM multidomain technique (MD-DRM) can be efficiently used together with a mass conservative in- terpolation method, to solve the Navier-Stokes equations at moderate and high Reynolds numbers.
