In virtually all complex fluids, this rich and unusual mechanical response originates from a microstructure that responds to different applied stress or strain in specific and varied ways. Thus understanding the microstructure – macroscopic behavior relationship is a crucial step for systematically designing complex fluid materials for novel applications. The complex fluid landscape can be subdivided based on the particle-level interactions that govern their underlying microstructure and the resulting macro rheology. For example, viscosity of a dense suspension of repulsive or neutral colloidal particles progressively increases with increasing the rate of deformation. This behavior is called Shear-Thickening behavior, and is best exemplified by someone’s ability to run on a pool of cornstarch and water, and sinking in while standing still. On the other hand, a distinct hallmark of attractive Brownian particles, even at small and intermediate concentrations,​ is their ability to self-assemble into percolated networks that span over the sample size. These structures show a rich time and rate dependent response to applied deformation/​forces such as yielding, shear banding, microphase separation and flow heterogeneities,​ etc. I will present a computational framework to bridge the gap between microstructure to macroscopic properties of complex fluids, using hydrodynamics and statistical mechanics: First I will discuss the role of hydrodynamics,​ friction and particle geometry/​deformability in shear-thickening fluids, and secondly, the role of microstructural evolutions of attractive systems in defining their mechanical response.
