Numerical Simulation of the Instability of a Non-Isothermal Liquid Film in Film Devices

This work presents results of numerical simulation the instability vertical liquid film flow at moderate Reynolds numbers in framework partial differential equation state free surface film. Equation coefficients include different physicochemical factors such as tension parameter and Marangoni parameter. Python scripts are used for computation wave characteristics, regions films state. Computational experiments were carried out water alcohol films. Results could be design or modernization existing equipment technological processes
