Current moving past an object in a wind tunnel (7)

Ross

I believe the answer is:

airflow

(Other definitions for airflow that I've seen before include "Current" , "Atmospheric stream across aircraft wing" , "Atmospheric movement" , "Motion around moving plane/vehicle" , "Fan" .)

I've seen this clue in the Sydney Morning Herald.
