@ARTICLE{Razzaghi, author = {razzaghi, ahmad and Rasouli, Saifollah and Maleki, Maniya and }, title = {Investigation of the dynamics of a flowing fluid film in gravity by moiré technique }, volume = {20}, number = {0}, abstract ={In this paper, the dynamics of a liquid thin film on a glass substrate has been measured by moiré technique. Light passes through two symmetric liquid thin films and we make the conventional counter fringes. Because the light passes through two liquid films, the ray tracing will be a difficult method. So we find an initial solution with some simple assumptions and then find the exact solution for the problem, with a Matlab program using recursion method. We can follow the formation of thin film and calculate the dynamics of thin film. }, URL = {http://opsi.ir/article-1-63-en.html}, eprint = {http://opsi.ir/article-1-63-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2014} }
