Abstract:Título: Estudo do efeito magnetohidrodinâmico em um eletrólito a partir do uso de um dispositivo ejetor eletromagnético Dedico este trabalho ao meu pai, Sooske Aoki, e a minha namorada, Andréia Cristina dos Santos, pelo apoio, incentivo, carinho e força recebidos, mesmo sabendo dos desafios que eu enfrentaria pela frente. AGRADECIMENTOS Agradeço ao meu pai, Sooske Aoki, pelo apoio, compreensão e confiança depositados em mim desde o começo, e pelo seu caráter e valor, que serviu e sempre servirá como um exemplo… Show more
“…They are present in various applications in the industry such as heating, pumping and levitation of liquid metals and are generated even in the core of the Earth, in which they are maintained by the incessant movement of fluid that is in this region. This phenomenon of interaction of magnetic fields with fluids is called magnetohydrodynamics or simply MHD [6].…”

“…For this, the fluid necessarily needs to be electrically conductive and non-magnetic, which limits its use to liquid metals, ionized gases and electrolytes. Quantitatively, this mutual interaction is based on the Laws of Faraday and Ampère and Lorentz forces for a current-carrying body [6] [5].…”
The present work studies the magnetohydrodynamic flow of a Newtonian fluid as a complementary case of the simple flow in a parallel plate channel. The effects of kinematic parameters and the influence of the transverse and uniform magnetic field on the fields of speed, flow and shear rate are analyzed. To solve the equations that govern movement, the Laplace Transform technique was used, and the Python programming language and wxMaxima program for the construction of graphs and convergence analysis, respectively. The results obtained were analyzed for different values of the Hartmann’s number and the limit case in which this parameter tends to zero compared to the simple flow in the absence of a field. The study showed the effect of the magnetic field on the velocity profile and other derived properties. And the limit case proved to be compatible with the case in which there is no magnetic field applied. In general, the work proved to be valid as a complementary study of the simple case, since the results obtained for the limit case clearly express its tendency towards the simple case presented by the literature.
