【 摘 要 】

We conduct a theoretical study ofthe dynamics of the concentration of nanoparticles in liquid-phase media under the influence of a laser light field. An exact solution of the nonlinear diffusion equation in the form of switching wavesis found. It is shown that, in the conditions of a fixed temperature and a nonlinear medium thermal conductivity, nanofluid becomes bistable.
