Abstract: A mathematical analytical modeling of induced current for electronic
anti-fouling technology is deduced in the present study, which can directly
measure induced electric field generated by excitation coil. Based on the
analytical expression of induced current, average power density is presented to
measure the force of electronic anti-fouling system acting on the aqueous
solution, and the functional relationship between average power density and
electronic anti-fouling system parameters is established, which can be made as
the basis of the system parameters optimizing. By discussing the functional
relationship it can be found: 1 when excitation signal frequency is higher than
a certain frequency value, the increase of excitation signal frequency can't
help increasing average power density effectively; 2 the coil radius is shorter
or coil turns are less then the average power becomes larger. Furthermore, for
proving the correctness of the proposed analytical model of induced current, an
exact 2D finite element method is used to calculate induced current in a real
electronic anti-fouling system, and the finite element calculation results can
fit well with the results calculated by the proposed analytical model of induced current.
