Research directions:

Investigation of the behavior of various liquids during the flow in nanotubes.

Three-dimensional modeling of the processes of molecular-dynamic interaction.

Main results:

On the basis of analytical and numerical modeling, the features of the flow of liquids in nanochannels were studied. For a number of types of liquid, a theory has been proposed that makes it possible to estimate the viscosity of a liquid depending on the force of interaction between liquid molecules and channel walls. The velocity profiles for the Poiseuille and Couette flows are obtained, and the processes occurring in the fluid are studied.
