Abstract

The process of applying a uniform thin film on a horizontal substrate is called spin coating. Spin coating relatively used in several industrial and scientific applications. In this study an attempted was made to numerically study the various factors affecting the spin coating process. CFD simulations were performed on 2D axisymetric geometry, VOF multiphase model was used to its work the liquid/gas interface, results from isothermal CFD simulation were first validated against theoretical values. Subsequently, CFD simulations were performed to determine the effects of flow important parameters. Parametric study was a alone to see the effect of spin, thermo viscosity and thermo capillary on spin coating process.
