Compared with the flow through an oblique shock, the flow through an expansion fan is

  • A.Turned away from itself and decelerated
  • B.Unchanged in direction
  • C.Turned away from itself and accelerated
  • D.Turned into itself and decelerated

Answer: C

A shock turns the flow into itself and slows it; an expansion does the reverse, turning it away from itself and speeding it up. Recognising which of the two a given corner produces is simply a matter of asking whether the surface turns away from the flow or into it.
