1.	Which of these distributions is required in the wake region of the lifting body?(a) Source(b) Dipole(c) Sink(d) DoubletThe question was asked during a job interview.The origin of the question is General Three Dimensional Flows-Panel Techniques topic in section Three-Dimensional Incompressible Flow of Aerodynamics
Answer» The correct choice is (B) Dipole The EXPLANATION is: LIFTING BODIES have a trailing edge which leads to a wake REGION. In the wake region, there is formation of vortices due to the disturbances in the flow. In this region, a dipole or vorticity singularity is used.
