Annexure-I Study of shear thinning and shear thickening in 2D fluids : Physics and Numerical Simulations Abstract Fluids, in general, under equilibrium conditions demonstrate constant transport coefficients, such as viscosity, thermal conductivity and diffusion coefficients. Let us consider a specific example, say, viscosity of a fluid. When a fluid layer is subjected to a shear rate (made to flow fast or slow), the fluid responds by developing a shear stress. The ratio of this shear stress to shear rate yields the viscosity coefficient. If this relationship is linear, so that for zero shear rate, the shear stress is also close to zero, such fluids are called Newtonian fluids. In other words, once the temperature and density of the fluid is fixed, the viscosity of the fluid does not dependent on how fast or slow the fluid is made to flow. However, there exists a class of fluids called Complex Fluids which are made up of more than one type of fluid particles, i.e., these fluids are heterogenous in nature. For these fluids, the relationship between shear stress and shear rate may not be Newtonian type. Several interesting Complex fluids have been synthesized in labs across the world as there are interesting applications for the same. One such example of a Complex fluid is a plasma with electrons, ions and micron-size conducting or dielectric spherical particles immersed in the background of electrons, ions and neutrals. This plasma, also called Complex Plasma, is known to behave in Non-Newtonian fashion, but this aspect of Complex plasma is not well studied. In this Project a literature survey of such fluids in general, including Complex plasmas will be performed along with understanding the numerical methods necessary to understand such fluids in Computer Simulations. The numerical methods learnt will be applied to a 2D Complex Plasma systems. Obtained results will be analyzed and new directions will be identified.
