Abstract
For eutectics of Ga/In/Sn, Ga/In/Zn, and Ga/In/Sn/Zn, room-temperature measurements are reported for viscosity and resistivity. Contact resistance, friction, and film thickness are calculated for tilted pads using these fluids as lubricants. Relative magnitudes of magnetohydrodynamic energy dissipation in an annulus is discussed in terms of a figure of merit, namely, the Hartmann number. The experimental findings show that the gallium alloys display the most favorable characteristics.<>
