Laminar flow of GNFs along Inclined Surface and Concentric Annulus — Lesson 4

This lesson covers the transport phenomena of Non-Newtonian fluids, focusing on the laminar flow of generalized Newtonian fluids along inclined surfaces and concentric annulus. It delves into the mathematical equations and principles that govern these phenomena, including the continuity and momentum equations. The lesson also discusses the constraints and assumptions used in these calculations, such as steady laminar flow, incompressible fluid, and the absence of gravity effects. It further explains the concept of shear stress and how it varies along the direction normal to the flow. The lesson concludes with an example problem that applies these concepts to a real-world scenario involving a polymer solution exhibiting power law behavior.
