Abstract

The problem of origination of regular convection in the layer of nanofluid with one free surface by the absorption of light waves with spatially periodic intensity distribution in the plane of the layer caused by the temperature dependence of the surface tension coefficient is studied. The profiles of velocity and temperature in the volume of medium are determined. It is shown that the response of the system on the influence of a light wave is maximal other conditions being equal, when the period of interference pattern is about twice as large as the layer thickness.
