Thin film equation
WebThe model is embodied in a third-order nonlinear film evolution equation, which is solved numerically. Variable wall-temperature boundary conditions are applied at the solid–liquid interface to account for conjugate heat transfer due to evaporative heat loss at the liquid–vapor interface. http://www.phys.ufl.edu/courses/phy2049/f08/lectures/lecture_wave_interference_2B.pdf
