Pattern formation in unstable viscous convective medium
The convection in a thin layer of liquid (gas) with poorly heat conducting boundaries and with temperature dependent viscosity are considered. The Proctor-Sivashinsky model is examined in order to study both the pattern formation and the second-order structural phase transitions as between patterns...

The Proctor-Sivashinsky model is examined in order to study both the pattern formation and the second-order structural phase transitions as between patterns with translational invariance as well as between structures with broken translational invariance but keeping a long-range order. The influence of the temperature dependence of viscosity on the process of pattern formation and structure transformations is discussed. Is shown that the temperature dependence of viscosity inhibits structural transition leading to formation of square cells. Initiallyquasi-stable structure of convective rolls becomes stable under this condition. |
