F. Stefani et G. Gerbeth, Velocity reconstruction in conducting fluids from magnetic field and electric potential measurements, INVERSE PR, 15(3), 1999, pp. 771-786
A possibility for the determination of velocity fields in conducting fluids
is presented. Applying a magnetic field from outside, electric and magneti
c fields are induced by the fluid motion. These fields can be measured at t
he walls and outside the fluid volume, respectively. The inverse problem of
reconstructing the velocity from the measured electric and magnetic fields
is solved using Tikhonov regularization.
