Instabilities and ordered patterns in nonisothermal ultrathin bilayer fluid films.
Evolution of ultrathin bilayer films under the joint action of van der Waals forces and Marangoni stresses in the presence of an inclined temperature gradient, is investigated. The problem is solved by means of a linear stability theory and nonlinear simulations. Two novel effects are found. First, linear analysis leads to the discovery of the phenomenon of "isotropization." Second, the formation of ordered structures that consist of equally sized droplets moving with equal velocities and located at equal distances from each other, is revealed.
