Abstract

In this work, we are interested in the mathematical study of the flow of a Newtonian Navier-Stokes fluid, coupled to the energy equation, in a domain with axial symmetry. The study consists first of all in reducing this problem, which is posed in a domain in dimension three (3-D), to a problem whose spatial domain is in dimension two, using the transformation of Cartesian coordinates in cylindrical coordinates, assuming that the problem data does not depend on the angle of rotation. The problem thus obtained is a so-called axially symmetric problem presenting a degeneracy on the axis of symmetry, hence the interest of this study. The study of this problem is the subject of the first part of this article which deals with the existence and uniqueness of the weak solution of the problem in a Sobolev space with appropriate weight. The results of this part have already been published by the same authors that we recall here with some slight modifications in order to facilitate the reading and understanding of the second part of the article. In this second part, we approach the existence and the unicity of the numerical solution of the posed problem. It is obtained using the Lagrange finite element method whose polinomial space is of degree one. The study in question highlights the necessary algebraic relations between the different physical parameters of the problem to which the flow in question obeys.
