Non-Newtonian Fluids: Heat Generation

This course covers the intricate transport phenomena of non-Newtonian fluids. It delves into the concept of free convection between two vertical plates, explaining the mathematical procedures used to obtain velocity profiles, volumetric flow rates, and friction factors. The course also discusses the additional considerations required for non-isothermal flow of non-Newtonian fluids, such as changes in viscosity and density due to temperature variations. It further explores the use of continuity equations, momentum equations, and energy equations in studying these flows. For instance, the course concludes with a detailed example of solving a problem involving laminar free convection flow between two vertical plates. Additionally, the course covers the concept of viscous heat generation, explaining how mechanical energy converts into thermal energy, leading to heat generation known as viscous dissipation. It provides examples of viscous heat generation in motor vehicles and conveyors in chemical industries. Lastly, the course covers the transport phenomena of non-Newtonian fluids, focusing on the temperature distribution in fluids confined between coaxial cylinders.
