STATE FUNCTION IN UNSTABLE CONVECTIVE MEDIUM

STATE FUNCTION IN UNSTABLE CONVECTIVE MEDIUM

Convection in a thin layer of liquid (gas) with temperature independent viscosity between poorly heat conducting boundaries is studied within framework of the Proctor-Sivashinsky model. We have shown by numerical simulation of the Proctor-Sivashinsky model that the state with certain topology can be...
