Resumo

LYRA, P. R. M.; LIMA, R. de C. F. de; CARVALHO, D. K. E. de  e  SILVA, G. M. L. L. da. An axisymmetric finite volume formulation for the solution of heat conduction problems using unstructured meshes. J. Braz. Soc. Mech. Sci. & Eng. [online]. 2005, vol.27, n.4, pp.407-414. ISSN 1678-5878.  http://dx.doi.org/10.1590/S1678-58782005000400009.

In this work, a finite volume formulation developed for two-dimensional models is extended to deal with axisymmetric models of heat conduction applications. This formulation uses a vertex centered finite volume method and it was implemented using an edge-based data structure. The time and domain discretization using triangular meshes is described in details, including the treatment of boundary conditions, source terms, and domains with multiple materials. The proposed formulation is validated and proves to be effective and flexible through the solution of simple model problems.

Palavras-chave : FVM; unstructured meshes; axisymmetric models; heat transfer applications.
