Abstract

This work studies the influence of the electromagnetic radiation of low intensity on the rheological parameters of water and water solutions of biologically active substance (NADH) which plays an important role in energy transforming processes in living organisms. The power spectrum of the thermal fluctuations of the free surface of liquid (capillary waves spectrum) has been measured using optical heterodyning method which makes it possible to detect the changes in frequency of the light scattered by moving liquid surface. The amplitude, the spectrum of spacial and time frequencies of thermal fluctuations (capillary waves) of free surface of water solution were investigated using optical heterodyning method. The viscosity and the surface tensions in the microlayer of water solution were determined from the obtained results. Water solution was dealt with as a low-viscosity Newtonian liquid in this analysis and was modelled by Navier-Stokes equation and incompressibility equation.
