Paper 1, Section I, D
Show that the flow with velocity potential
in two-dimensional, plane-polar coordinates is incompressible in . Determine the flux of fluid across a closed contour that encloses the origin. What does this flow represent?
Show that the flow with velocity potential
has no normal flow across the line . What fluid flow does this represent in the unbounded plane? What flow does it represent for fluid occupying the domain ?
