Growth of a thin film accompanied by chemical reaction

Growth of a thin film as a result of mass transfer from a limited fluid poc ket has been modeled. The numerical solution of the moving-boundary problem has been obtained by freezing the time-dependent boundary through Landau t ransformation. Effects of various physicochemical parameters on the growth of film with time have been I,resented. Although originally developed for l iquid films, the model successfully predicts the experimentally observed qu alitative features of the growth of a solid him. This success takes us a st ep closer to the larger goal of developing a unified model for growth of al l kinds of thin films, involving diffusion as the principal mechanism of tr ansport.
