  7. Abstract:
  8. Surface phenomena and dynamic Interfacial properties play an important roles in gas- liquid and liquid-liquid multiphase process from various industrial applications to understand fundamental phenomena. However, there is no experimental equipment and efficient methods for quantitative and detail investigation of interfacial properties under fast and non-equilibrium dynamic condition due to mobility and refreshing of interface (such as rising bubble). Also existing models accompanied with a lot of simplifications which is not yet validated with a proper experimental data. development of laboratory equipment base on measuring momentary capillary pressure and presenting a new experimental method "bubble in flow field" by Dr.Lotfi and partners for the first time, quantitative study of dynamic adsorption layer in multiphase systems and more detail investigation of common theories became possible. In this project by simulation of new experimental method “ bubble in flow field” with fluent the common software investigation of dynamic multiphase systems have been proper to predict interfacial properties variation such as surface tension and other properties by increasing flow rate on bubble surface and surfactant concentration variation
