E. Tzirtzilakis, Auteur ; N. G. Kafoussias, Auteur Article en page(s) : pp. [011702-1/8] Note générale : Physique Langues : Anglais (eng) Mots-clés : FHD  Magnetic  fluid  Three-dimensional  flow  Stretching  sheet  Low  curie  temperature  Moderate  saturation  magnetization Index. décimale : 536 Chaleur. Thermodynamique Résumé : The three-dimensional laminar and steady boundary layer flow of an electrically nonconducting and incompressible magnetic fluid, with low Curie temperature and moderate saturation magnetization, over an elastic stretching sheet, is numerically studied. The fluid is subject to the magnetic field generated by an infinitely long, straight wire, carrying an electric current. The magnetic fluid far from the surface is at rest and at temperature greater of that of the sheet. It is also assumed that the magnetization of the fluid varies with the magnetic field strength H and the temperature T. The numerical solution of the coupled and nonlinear system of ordinary differential equations, resulting after the introduction of appropriate nondimensional variables, with its boundary conditions, describing the problem under consideration, is obtained by an efficient numerical technique based on the common finite difference method. Numerical calculations are carried out for the case of a representative water-based magnetic fluid and for specific values of the dimensionless parameters entering into the problem, and the obtained results are presented graphically for these values of the parameters. The analysis of these results showed that there is an interaction between the motions of the fluid, which are induced by the stretching surface and by the action of the magnetic field, and the flow field is noticeably affected by the variations in the magnetic interaction parameter beta. The important results of the present analysis are summarized in Sec.
