Laminar-turbulent transition flow phenomena on a flat plate in a low-speed wind tunnel at different Reynolds numbers were studied numerically. The flow calculation is based on an inviscid/boundary layer interaction method with modified Abu-Ghannam/Shaw(AGS) transition criterion. The test section has non-symmetrical contoured walls, and the plate is located biased the bottom side with a height ratio of 26:14. In test case of steady flow, a laminar-turbulent transition takes place and a small separation bubble occurs on the upper side of the plate, when the inlet Reynolds number is as small as 0.631x10 -6. The predicted transition location agrees well with that of the test results, but the separation bubble is hardly to see from the calculated velocity profiles though the printed data of velocity in this region do show the negative values. The further numerical predictions with different Reynolds numbers corresponding to the incoming flow velocities show that when the Reynolds number is greater than 1.379x10 6, the separation bubble does not occur, which is coincident with the experimental results. The influence of the side wall geometry on the transition on the plate is also studied.
