Vortex Flows and the Rolled Up Vortex Wake

  • Josef Rom


The trailing vortex wake behind the lifting wing is an excellent example of the natural tendency of free vortical shear layers to roll up into well-defined concentrated vortices with the essentially inviscid outer flow rotating around an inner viscous core. Such is the case when the well known tip vortices are established in the wake of high AR lifting wings. High speed computers provide the means for calculating the characteristics of the complete flow field over the wing as well as its wake and the rolled-up tip vortices. These calculations will be presented and discussed in the following chapters. However, before diving into the details of the calculations, it is of particular interest and importance to gain some insight into the flow field over wings and their wakes. This can best be done by examining analytical solutions, such as those developed by Sprieter and Sacks (1951), to the problems of simulating the main features of the rolled-up vortex flow.
