On the film thickness in the film theory

WebIn fluid mechanics, the thin-film equation is a partial differential equation that approximately predicts the time evolution of the thickness h of a liquid film that lies on a surface. The equation is derived via lubrication theory which is based on the assumption that the length-scales in the surface directions are significantly larger than in the direction normal to the … WebFilm thickness definition: A film consists of moving pictures that have been recorded so that they can be shown at...
