Numerical calculation of ferrofluid optical transmission evolution after magnetic field switch-on

Sanz-Felipe, Ángel (Universidad de Zaragoza) ; Martín, Juan Carlos (Universidad de Zaragoza)

Resumen: A method to calculate the optical transmission evolution of a ferrofluid after exposure to an external magnetic field is proposed. In the first part of this work, a simulation program is employed to simulate the nanoparticle rearrangement for different particle concentrations and different magnetic field intensities. In the second part, the simulated particle distributions'' optical response is determined by means of a mixture law, which avoids typical huge computational times associated to this stage of the calculation. Experimental and simulated results with both parallel and perpendicular magnetic field orientations with respect to the incident light are compared. A significant correlation is obtained, which proves the usefulness of the proposed method in order to obtain the optical transmission evolution of a ferrofluid.
