Internal Flows and Boundary Layers

This lecture covers the analysis of internal flows and boundary layers in heat transfer. Topics include hydrodynamic entry length, laminar and thermal entry lengths, mean temperature, heat transfer coefficient, and correlations for the Nusselt number. The presentation delves into the thermal boundary layer, energy balance, and the importance of axial conduction. The lecture also discusses the analytical solutions for laminar flows, the impact of viscous dissipation, and the numerical solutions for flow problems. Various concepts such as the Nusselt number, thermal fully developed flow, and the solution techniques for internal energy balances are explored.
