The Effects of Finite-Amplitude Disturbances on the Mean Flow Profiles in a Laminar Boundary Layer,

摘要

Recent advances in boundary layer control technology have greatly enhanced the feasibility of designing a high speed, high performance, laminar-flow vehicle. The potential improvement of the vehicle performance through the use of boundary-layer control depends strongly on the ability to understand the physics of the transitional and pre-transitional boundary layer and to use this understanding to predict and control the occurrence and location of boundary-layer transition. To date, empirical correlations of the location of transition have been most commonly used schemes in most design procedures. This report specifically addresses this problem of improving the present capability for predicting the transition onset analytically.
