Abstract: Abstract The first part of the chapter provides a review for mass, momentum, and energy conservation, as well as turbulence theory and modeling. Then, the historical development and importance of the Reynolds number (Re) is firmly established, leading to guidelines for calculating Re for many useful engineering geometries. Fully developed laminar and turbulent flow is described, as well as insights regarding the turbulent kinematic viscosity. Finally, isotropic turbulence and Taylor eddy theory are introduced, to lay a foundation regarding their merit and practical applications in CFD modeling; this development culminates in Sect. 3.7, where numerous practical drag reduction and heat transfer applications are described in more detail.
