Analytical and numerical analysis of velocity and temperature fields for laminar forced heat convection in concentric annular tube [articol]

Abstract

This paper presents a study of the dual reciprocity boundary element method (DRBEM) for the laminar heat convection problem between two coaxial cylinders with constant heat flux boundary condition. DRBEM is one of the most successful techniques used to transform the domain integrals arising from the nonhomogeneous term of the Poisson equation into equivalent boundary only integrals.
