Nonlinear model for Marangoni convection.
We have constructed a Lorenz-like model for Marangoni convection with finite wave number in large aspect ratio situations. Within the model, there is exchange of stabilities at the onset of convection and beyond the onset there is onset of oscillations due to the presence of surface fluctuations. The oscillations become chaotic as the Marangoni number is increased.
