NONLINEAR DEVELOPMENT OF THE MARANGONI INSTABILITY IN LIQUID FILMS


A nonlinear mathematical model of the state of the free surface of a nonisothermal liquid fi lm is presented. The basic wave characteristics and the liquid fi lm free surface state have been calculated for moderate Reynolds numbers in the presence of Marangoni instability. A nonlinear parabolic equation for the amplitude of the envelope of wave train and the results of computational experiment on the nonlinear development of Marangoni instability in liquid fi lms
are presented.
