摘要：
A half-scale model of a portion of the Langley 8-Foot Transonic Pressure Tunnel was used to conduct some turbulence reduction research using screens, honeycomb, and combinations thereof. The experimental results are compared with various theories. Screens alone reduce axial turbulence more than lateral turbulence; whereas, honeycomb alone reduces lateral turbulence more than axial turbulence. Because of this difference, the physical mechanism for decreasing turbulence for screens and honeycomb must be completely different. Honeycomb with a downstream screen is an excellent combination for reducing turbulence.
