In 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 surface. In the non-dimensional form of the Navier-Stokes equation the requirement is that terms of order ε and ε Re … WebThe thin film was deposited on glass substrate by thermal evaporation method using the Hind-High vacuum coating unit (HIND-HIVAC Model 12A4D) from bulk As 40 Se 50 Ge 10 sample two years ago.
