Eunhye Kim (Suwon Univ.) Complex fluids are single or multiphase fluids whose components couple different length scales. Many are composite materials having internal coexistence of two or more than two phases, e.g. solid-liquid, liquid-gas, liquid-liquid; familiar examples are found broadly in our daily products such as foods, shampoo and cosmetics. Due to these utilities, numerical investigation to explore a new trend of complex fluids has been of great interests last two decades. Besides, the physics is barely understood in terms of dynamics. In this seminar, I will talk about the numerical results of microstructures and dynamics of colloidal complex fluids: ferrofluids (magnetic colloids in a single fluid) and colloidal stabilized emulsions using an immiscible binary fluid and non-magnetic/magnetic colloids. First, I will describe the hybrid method based on lattice Boltzmann method has been used to simulate all systems. Then the results will be discussed. |
