Question

A combination of uniform flow and doublet flow gives ______________

(a) flow past a circular cylinder

(b) flow past a wedge

(c) flow past a plate

(d) flow over any body

The question was asked in quiz.

This interesting question is from Nonlifting Flow over Cylinder in section Inviscid & Incompressible Flow of Aerodynamics

Answer 1

The correct option is (a) flow past a circular cylinder

To explain: In the above figure, the first diagram shows the uniform flow whereas, the second one shows the doublet flow (source sink combination of equal strength). The combination of these two leads to the flow past a cylinder.
