Unsteady Boundary LayersThe examples of solutions of the boundary–layer equations treated up until now have been those for steady flows. Although it is steady flows which are by far of greatest importance in practical applications, in this chapter we will treat some cases of boundary layers which vary in time, that is, unsteady boundary layers.

https://doi.org/10.1007/978-3-663-02677-8the last chapter, the limiting solution Re = ∞ is often a good approximation. A notable shortcoming of this limiting solution is that the no–slip condition is not satisfied, i.e. the velocities at the wall are not zero but are finite. The viscosity must be taken into account in order to satisfy the no–slip condition.

As the Reynolds number is increased, both internal flows through pipes and channels and external boundary–layers flows past bodies exhibit a noticeable change from a laminar flow form to a turbulent flow form. This . from laminar to turbulent flow, also called the . is of fundamental importance for the whole science of fluid mechanics.

https://doi.org/10.1007/978-3-663-02677-8ible. It is only since the 20. century that the effects of viscosity and compressibility have been taken into account in any great way. In the flow of inviscid fluids, no tangential forces (shear stresses) exist between adjacent layers; only normal forces (pressures) do. This is equivalent to saying
