Étude expérimentale et numérique de la convection thermomagnétique dans un fluide non électroconducteur

We present an experimental and numerical study of convection driven by a central heat source in a vertical and cylindrical cavity with a higth aspect ration, filled by air and submitted to the action of non homogeneous intence magnetic field. We show how the magnetization force applying on oxygene is able to intensify, reduce, stop or even reverse the natural convection fluid flow.
