- Abstract
It is experimentally demonstrated that a nonstationary motion of the convective rolls in a nematic liquid crystal is accompanied by the generation of acoustic waves. Informative parameters of the acoustic emission exhibit correlations with the type, morphology, and dynamics of the dissipative structures appearing in a cell with a large aspect ratio during increase in the critical parameter. We show a principal possibility to provide a quantitative description of the chaotic dynamics of dissipative structures in the space of parameters of the observed acoustic emission.
