課程概述	Thus, this course will be divided evenly into three parts. The first two will cover the classical topics in the fields of granular flows and suspensions. Though both fields require extensive theoretical background, we will focus on the physical meaning and the concepts behind the existing theories and learn from dimension analysis, if applicable. The learning should help to understand the third part–the recent theories on solid-liquid flows where both the solid and the liquid possess comparable inertia in the mixture. During the course, we will also cover the topics related to particle-level interactions, including contact mechanics and the interaction between a single particle and its surrounding flow.
課程目標	Obtain general understanding of the bulk behavior of solid-liquid mixtures; understand the general concepts behind the available models, strengthen theoretical background on particle-level mechanics (both solid & fluid); develop a sense of studying complex systems
課程要求	engineering mathematics, fluid mechanics (preferred), solid mechanics (preferred), statistical mechanics (not strictly required)

Week 3	3/08	Granular flow avalanches in fluids; Submarine granular flows down inclined plane [pay attention to flow phenomenon and scaling analysis]
Week 4	3/15	Relaxation dynamics of water-immersed granular avalanches [Modeling and experimental data --pay attention to velocity depth profile and the feasibility of the proposed model]
Week 5	3/22	Effects of lateral walls and interstitial fluid on the granular flow motion in a rotating drum [pay attention to flow rheology changes with respect to the two factors]
Week 6	3/29	Effective viscosity of a fluid Containing small solid spheres or drops of another Fluid [check the mathematical formulation and final results as a function of volume fraction of the disperse phase]
Week 7	4/05	Interesting phenomenon: a dilute dry flow around an immersed cylinder and the resulting 'drag' and resulting sound speed [pay attention how the authors use our basic understanding of gas dynamics to explain the observations]
