Concepts of continuum mechanics are introduced, specifically the fluid dynamics of non-Newtonian and linear viscoelastic fluids. Material functions, constitutive equations and rheometry and experimental methods for measuring material functions (rheometry) are discussed. Knowledge of linear differential equations \[such asMATH 319or320] and fluid mechanics \[such asM E 363] or momentum transfer \[such asCBE 320] required. ### requirements text Graduate/professional
