Analytical solution of a unidimensional model of a SiO 2 -water nanofluid system exposed to two phase-shifted alternating electric fields. The fields are harmonically coupled such that the frequency of one field is double that of the other without any direct current bias. The solution was then compared to a pseudo-experimental design. Further investigation of the dependence of motion on the particle dimension and temperature is also presented. The results show that the motion of the silica nanoparticle can be controlled by the use of mixed electric fields, and that beyond Brownian motion, the size of the nanoparticle, field amplitudes and frequency, and the surface charge of the silica are the main parameters that control its motion within the fluid. In addition, enhanced motions are prominent at odd harmonics compared with even ones. The knowledge advanced in this work affords nanomanufacturing applications, such as electrodeposition and the development of special paints, adhesives, and smart coolants with controllable thermal properties.
