The experimental results of heat transfer enhancement in forced liquid metal flows due to the application of a transverse magnetic field are reviewed. It is shown that in nonconducting channels the heat transfer enhancement is due to the creation, by an inverse energy transfer process, of a strong anisotropic turbulence. For this to happen it is necessary to use flow perturbing means (such as grids) which inject to the flow turbulent energy in the form of small scale vortices whose axes are parallel to the field direction. In conducting channels, on the other hand, the magnetic field excites the turbulence without the need for external flow perturbing means. If persisting to the M > 300, Re > 2 x 104 range arrived at the present experiments, this magnetic field enhanced anisotropic turbulence and heat transfer could significantly improve the design and performance of liquid metal cooled fusion reactors.
