  1. Congratulations to Amir Tohidi on his successful completion of the PhD degree. His advisor, Prof. Mostafa Hosseinalipour was Prof. Mujumdar's PhD student at McGill University.
    Amir Tohidi received his Ph.D. from Iran University of science and Technology in 2013. He was Dr. Hosseinalipour’s Ph.D student of mechanical engineering in IUST (Iran University of science and Technology) working on rheological models describing dough behavior, numerical simulation and experimental methods applied to dough development. A part of his research project was to devise and to manufacture a novel dough mixer based on chaos theory and registered as a new patent in Iran. It was devised based on a simple geometrical perturbation to induce chaotic advection in order to improve mixing performance which is considered as a hardship in the mixing phenomena of highly viscose materials. High viscous fluids have various applications in industries such as polymer production, food industry and emulsion. Due to high energy consumption, the use of turbulent flow is not feasible or requires high viscosity. In other hand, the use of high speed blades may damage macromolecules of these fluids. Recently researchers are considering generating chaotic advection in these fluids, so as to increase the mixing and heat transfer rate in them. In a chaotic flow, closely spaced particles will diverge exponentially leading to an increased interface and thusly higher rate of mixing and heat transfer. Studied show that simple changes in geometry and boundary conditions can result in a chaotic flow and also improve chaos in the stokes flow. Considering that stokes equations are valid for the dough in the intended mixer, the effect of physical and geometrical parameters on chaotic advection has been evaluated in this thesis. This mixer has been evaluated in the CAE center 
    of Iran University of Science and Technology and has been proved to be chaotic by using numerical simulation and experimental tests.
