A study on Marangoni convection by the variational iteration method [PDF]
AIP Conference Proceedings, 2012 In this letter, we will consider the use of the variational iteration method and Padé approximant for finding approximate solutions for a Marangoni convection induced flow over a free surface due to an imposed temperature gradient. The solutions are compared with the numerical (fourth-order Runge Kutta) solutions.
