BIOE 3310 Lecture 0 - Fluid Definition, Shear Stress, Viscosity, and Velocity Gradient

Lecture 1 of BIOE 3310 with Prof. Lannin at Northeastern University Topics: Definition of a Fluid What is shear stress? What is shear strain? Shear strain rate? Units and dimensional homogeneity Constituitive relationships (shear stress to shear strain for solids and shear stress to shear strain rate for fluids, material properties) Newtonian fluids and viscosity Reynolds number Relationship of velocity gradient to shear strain rate
