Forced Convection Theory: Thermal Boundary Layer Equations

This lecture covers the theory of forced convection, focusing on the thermal boundary layer equations and the heat transfer between a solid and a fluid in motion at different temperatures. It explains how heat is transferred through both diffusion and advection during convection, and discusses the concepts of velocity boundary layer, Newton's law, convection coefficient, and the Prandtl number. The lecture also delves into the physical properties of the boundary layer, the importance of geometry and flow characteristics in convective heat transfer, and the dimensionless numbers related to inertia and viscous forces. Additionally, it explores the significance of the Prandtl number in determining the thickness of the thermal boundary layer relative to the velocity boundary layer.
