Heat Transfer
Heat transfer lectures by Professor Josua Meyer (2014). Topics covered in the lectures include: transient or unsteady heat conduction, convection heat transfer, external and internal forced convection, heat exchangers, thermal radiation including atmospheric and solar radiation. The lectures are based on the textbooks of White (8th ed) and Cengel and Ghajar (4th ed) and were presented as part of a heat transfer class to the fourth year students of the Department of Mechanical and Aeronautical Engineering, University of Pretoria.
| Lecture 22 - Fundamentals of Convection Heat Transfer (2of3): Boundary Layers |
This lecture continues on the fundamentals of convection. The following was discussed: velocity boundary layer, wall shear stress, thermal boundary layer, heat transfer coefficient, Prandtl number, laminar and turbulent flow, Reynolds number, heat and mass transfer in turbulent flow, solutions of convective equations for a flat plate, continuity-, momentum-, energy equation, and Blasius.
