Question

Name and describe each of the five parts of a standard wind tunnel.

Answer 1

Settling chamber-settle and straighten the air through the use of panels with honeycomb-shaped holes or a mesh screen.

contraction cone-a constricted space that greatly increases airflow velocity.

diffuser-conical shape that widens, and thus, smoothly slows the air's velocity without causing turbulence in the test section.

test section-where sensors record data and scientists make visual observations.

closed circuits-vals that send the air around and around the same path  using vanes and honeycomb panels to precisely guide and direct the flow.
