Abstract

We study the theory of the dynamics of the concentration of nanoparticles in a liquid-phase environment under the influence of a light field. An exact solution for the nonlinear diffusion equation was found in the form of switching waves. It is shown that under the conditions of a stationary and nonlinear temperature coefficient of thermal conductivity in the medium, nanofluids become bistable. A comparative analysis of linear and non-linear approaches to solving the diffusion equation is given.
