Adrian Bejan I Boundary Layer Theory, from Convection

Adrian Bejan discusses the foundations of Boundary Layer Theory, focusing on two-dimensional steady-state external flow concepts, the importance of temperature differences in heat transfer, and the historical development of fluid dynamics equations, notably the Navier-Stokes equations. He emphasizes the significance of scale analysis in simplifying these equations and deriving essential characteristics such as skin friction and the behavior of the boundary layer in fluid mechanics.
