  3. Abstract:
  4. An extensive experimental test to study the flow behavior over a rectangular wing in the subsonic wind tunnel in Iran was conducted. The tests included, surface pressure measurements at three locations and wake study at different angles of attack and free-stream Reynolds number. Further, to investigate the sidewall effects on the model pressure and wake, suction were applied at the wing root, where the model was attached to the tunnel wall. Suction affected surface pressure at all three locations by increasing the model pressure peak, preventing separation near the T. E., etc. at low angles of attack. However at moderate to high angles of attack, suction affected only the root pressure distribution
