  7. Abstract:
  8. Understanding the hydrodynamic and physical chemistry basis of surface phenomena is very important for many branches of basic science like Chemical Engineering, Mechanics, Space Engineering, and Material Engineering in the level of fundamental studies and applications. In addition to the common technologies, the role of surface phenomena in novel technologies is also very essential. For example, nanotechnology, chemical or physical sensors, or micro electrical systems in which surface phenomena is playing a main role. Therefore, understanding the basis of surface science is very important for any development in many industrial and fundamental studies. The main topic of this thesis which is a mutual research study between Sharif University of Technology in Tehran and the Max Planck Institute of Colloids and Interface Science in Potsdam/Golm, Germany is to investigate the behavior of fluid surfaces under dynamic conditions. In general, two main directions are followed. The first concern in this thesis is to better understand the fundamental knowledge of surface science, to be applied for different applications. For this aim, many experimental studies are performed to understand the kinetics of adsorption of surfactant molecules at the fluid interfaces and the surface dynamic behaviors in pure systems. The analysis of experimental results not only improves our knowledge about surface science, but also demonstrates the complexity of such systems in different conditions. The main experimental investigations are performed in MPI. In addition, Computational fluid Dynamics Simulations are applied to the aim of studying the complexity of systems. In this study, the main attempt was to combine experimental studies and numerical simulations to better understand the main concepts. CFD simulations are partly performed in Sharif University, in the Max Planck Institute in Golm and also in close cooperations with the groups of Prof. D. Bothe and Dr. E. Bonaccurso in Technical University of Darmstadt in Darmstadt, Germany. The second attempt in this research study is to improve the novel experimental techniques and protocols applied to the aim of fundamental studies of surface science. Any development in science and industries is not possible without attempts in the development of instruments applied in this aim. Therefore, a part of our research is performed in a close cooperation with Dr. J. Kragel and Dr. A. Makievski from the Sinterface Technology in Berlin, Germany as a leading company in the development of experimental setups mentioned and used in this thesis. In additions, supports from Dr. V.I. Kovalchuk and N. Kovalchuk from the Institute of Biocolloid Chemistry in Kiev, Ukraine, and Dr. J. Ferry from the Lafayette College in Pennsylvania, USA for a part of this research are highly acknowledged. Also, a part of the experiments are performed in a research mission to the research center of Statoil Company in Porsgrunn, Norway and supports from Dr. R. Orr are highly appreciated. At the end, I’d like to highly appreciate my supervisors, Prof. D. Bastani, Prof. R. Miller and Dr. A. Javadi for their nice and helpful cares, supports and advices at any stage of this research. Also supports from my friends and professors in Sharif University of Technology, my friends and professors from the MPI in Golm and all the other friends supported me in this way are highly acknowledged.
