A Comment Upon Previous Studies on 3-D Boundary Layer Transition

Authors: Melda Özdinç ÇARPINLIOĞLU

Abstract: The common feature of the experimental studies upon 3-D boundary layer development on swept flat plates cited in the available literature is the application of streamwise and/or spanwise pressure gradients. In fact; presence of the pressure gradients was suggested to be vital for having crossflow effective in 3-D boundary layer transition. In the presented paper here, this idea is questioned evaluating the results of an experimental investigation conducted on swept flat plates under the absence of a pressure gradient. In this context the influence of plate sweep angle \lambda; itself on transition is determined simply through the natural transition measurements on the test plates with different \lambda.
