Paper Abstract

It were analyzed the nonlinear optical methods of diagnostics of binary mixtures - the thermal lens method and dynamical holography method. In two-component fluid (binary mixture) the heat flow can cause concentration stream arising from occurrence of thermodiffusion phenomenon (Soret effect). As a result these phenomenon changes the magnitude of the transport coefficients of the mixture. It was developed the theory of the light induced heat and mass transfer, taking into account the cross interaction between the heat and mass flows as well as the presence of optical feedback. The results are relevant to the optical diagnostics of the binary liquid mixtures and nanofluids.
