Heat Transfer: Internal Flows

This lecture covers the analysis of internal flows in heat transfer, focusing on laminar hydrodynamic and thermal entry lengths, mean temperature, and heat transfer coefficient. It discusses the thermal boundary layer, energy balance, and the importance of axial conduction. The lecture also delves into correlations for the Nusselt number, fully developed Nusselt number, and analytical solutions for flow problems. Numerical solutions, position nodes, and the solution process for energy balance are explored. The lecture concludes with a detailed examination of the Nusselt number, surface heat flux, and the heat transfer process in internal flows.
