This lesson covers the transport phenomena of Non-Newtonian fluids, focusing on the momentum boundary layer thickness. It begins with a recap of the previous lecture, discussing the basic aspects of a momentum boundary layer and how the velocity gradient changes. The lesson then delves into the integral momentum equation for boundary layer flows, explaining its validity for both Newtonian and non-Newtonian fluids. The lesson also discusses the integral energy equation for heat transfer in boundary layer flows. The lesson concludes by explaining how to calculate the boundary layer thickness for Newtonian and power law fluids, and how to determine the shear stress in fluid at the surface.

The integral momentum equation is valid for both Newtonian and non-Newtonian fluids, with the only constraint being that the flow is steady and incompressible.

The velocity gradient changes from the solid surface to a far away distance when moving in a vertical direction.

The boundary layer thickness for Newtonian and power law fluids can be calculated using specific equations.

The shear stress in fluid at the surface can be determined, which is crucial for calculating the drag force and drag coefficient.
