ABSTRACT:
A portable wind tunnel features a tubular test section which has a constant cross-sectional area. The smaller end of a diffuser, which resembles a funnel, is attached to one end of the test section. The other end of the diffuser has a larger cross-sectional area. A flow generator, such as a fan, creates an airflow through the test section. The flow generator has an air inlet and an air outlet. A flow straightener is situated upstream from the air inlet of the flow generator normal to the direction of the airflow. The smaller end of a constrictor, which also resembles a funnel, is attached to the other end of the test section. The other end of the constrictor has a larger cross-sectional area.
