The main advantage of a closed-circuit wind tunnel is

  • A.That it needs no drive fan
  • B.Better flow quality and lower power
  • C.Lower capital cost
  • D.A smaller floor area

Answer: B

Recirculating the air lets the tunnel recover much of the kinetic energy each pass, so the drive power for a given test section is far lower, and the flow can be conditioned consistently. The penalties are cost, floor space and the need to remove the heat the fan adds.
