To determine boundary-layer characteristics on a body, for example the boundary-layer thickness, we must first know the potential-flow solution. The information used from the
Potential-flow solution is:
A) The lift and drag acting on the body
B) The pressure and velocity at the boundary of the body
C) The shearing stress acting on the boundary of the body
D) The normal and shearing stress acting on the boundary of the body

Question

Quizplus · Accepted Answer

he pressure and velocity at the boundary of the body
The velocity at the outer edge of the boundary layer is assumed to be the velocity at
the wall obtained from the potential flow solution. The pressure is needed since the
Navier-Stokes equation, which must be solved to obtain the solution to the
boundary-layer problem, includes the pressure gradient.
