Paper Abstract

It were analyzed the Dufour effect in the transparent nanosuspension in a light field. The space non-uniform light field generates the nanoparticles flow due to electrostrictive gradient forces. The concentration flow generates the thermal flow due to the Dufour effect and therefore the thermodiffusion (Soret effect). The dynamic holography method is proposed for the investigation of those phenomena. The Dufour thermal response and the thermodiffusion phenomenon both change the magnitude and relaxation time of the electrostrictive hologram. The results are relevant to the optical diagnostics of the nanosuspensions and nanofluids.
