Question

In a wind tunnel, the honeycomb has a longer length that reduces the ______ velocity components of the flow with minimal pressure drop in the stream wise direction.

• A. longitudinal
• B. axial
• C. traverse
• D. lengthwise

Hint:

Using honeycomb structures in wind tunnels is crucial for achieving a laminar flow, which is essential for precise aerodynamic measurements in automotive and aerospace applications.

Answer 1

The Correct Option is B

In wind tunnel testing, the honeycomb structure is used to straighten and smooth the airflow, reducing axial velocity components. This ensures that the flow has minimal turbulence and pressure drop along the streamwise direction, aiding in more accurate aerodynamic testing.
