  4. Abstract:
  5. In this investigation an intensive experimental study was conducted to study the flow quality in a test section of a low speed, V∞ = 10 - 100, closed return wind tunnel. An interesting result was obtained when a trip strip, a guitar wire with D= 1.14mm, was installed near the end of the contraction region. Addition of this trip wire resulted in a turbulent reduction almost at all speed ranges along the entire test section. Further, it smoothness the variation of turbulent intensity along the test section too. Velocity profiles along the tunnel wall at various speeds using a rake were measured with and without the trip wire. In addition, pressure contours at different location of the test section was measured too. Copyright © 2004 by ASME
