Channel, Tube, and Film Flow
In previous chapters, we have derived differential equations governing the motion of an incompressible Newtonian fluid by requiring mass conservation and enforcing Newton’s second law for the motion of fluid parcels. The govern- ing equations are accompanied by initial, boundary, and interfacial conditions. In this chapter, we proceed to derive analytical and semi-analytical solutions for an important class of steady and unsteady flows with rectilinear and cir- cular streamlines. The engineering significance of these flows combined with their ability to demonstrate the salient mechanisms of momentum and vorticity transport at steady and unsteady state justify an in-depth study.
