The first goal is to expand the spectrum of application of the so called Generalized Integral Transform Technique (GITT), dealing with a multiphysics formulation, while further demonstrating the relative merits of the proposed eigenfunction expansion approach in handling highly nonlinear and coupled systems of partial differential equations. The second goal is to provide a set of benchmark results in this important application for quantities of practical interest in determining the heat transfer rates, such as the average Nusselt number. The two-dimensional steady state equations are written in dimensionless form using the streamfunction-only formulation and are subsequently solved with the GITT approach, under automatic relative error control. Critical comparisons are performed against previous work reported in the literature, both computational and experimental, together with the corresponding physical interpretations, for different values of the governing parameters, such as Grashof number, Hartmann number, Prandtl number, and magnetic field inclination angle.Submitted by Jairo Amaro (jairo.amaro@sibi.ufrj.br) on 2019-06-10T15:25:14Z No. of bitstreams: 1 8-2017_Analysis-of-magnetohydrodynamic-natural-convection-min.pdf: 436507 bytes, checksum: 271bc51a9712fa265e291fb54b2b4bee (MD5)Made available in DSpace on 2019-06-10T15:25:14Z (GMT).
