Experimental evidence of Alfvén wave propagation in a Gallium alloy

10p.International audienceExperiments with a liquid metal alloy, galinstan, are reported and show clear evidence of Alfvén wave propagation as well as resonance of Alfvén modes. Galinstan is liquid at room temperature, and although its electrical conductivity is not as large as that of liquid sodium or NaK, it has still been possible to study Alfvén waves, thanks to the use of intense magnetic fi elds, up to 13 teslas. The maximal values of Lundquist number, around 60, are similar to that of the reference experimental study by Jameson [1]. The generation mechanism for Alfvén waves and their refl ection is studied carefully. Numerical simulations have been performed and have been able to reproduce the experimental results despite the fact that the simulated magnetic Prandtl number was much larger than that of galinstan. An originality of the present study is that a poloidal disturbance (magnetic and velocity fields) is generated, allowing us to track its propagation from outside the conducting domain, hence without interfering

“…The wall thickness is 2 mm. During an experiment, the box is placed in the bore (130 mm of diameter) of a powerful (12 MW ) resistive electromagnet (magnet M5), facility of the LNCMI in Grenoble [22]. The electromagnet produces a magnetic field of intensity between 0 and 13 T aligned with the axis of the cylindrical container.…”
