Turbulent Boundary Layers

Description	Our consideration of convective transport has so far been limited to cases where the flow field is laminar. Most transport operations involve not laminar, but turbulent flow. The reason behind this is simple: transport coefficients in turbulent flow can be an order of magnitude, or more, larger than the corresponding coefficients for laminar flow. This difference can be traced to a difference in the structure of the laminar and turbulent boundary layers. Unfortunately, we still have trouble simulating turbulence directly from the Navier-Stokes equations. Thus, our knowledge of the turbulent boundary layer's structure is still largely experimental. In this chapter, we will discuss how we represent turbulent flow, the difference between turbulent and laminar boundary layers, and how this difference leads to changes in the values of the transport coefficients. By the end of the chapter you should know how to diagnose a system and predict whether the flow will be laminar or turbulent; how to evaluate friction factors, the heat transfer coefficient, and mass transfer coefficients in turbulent flow; and how to solve several simple, problems that involve turbulent flows.
