Abstract

An accurate, efficient, and automatic laminar-to-turbulent transition prediction frame- work is developed. The framework includes a laminar boundary layer code and a linear stability code coupled with a Reynolds-Averaged Navier-Stokes (RANS) solver. The framework is able to analyze transition induced by contamination at the leading edge, Tollmien-Schlichting waves or crossflow instabilities and uses a correlation relationship to predict the transition location and transition length for laminar separation transition. Three typical configurations with experimental data from subsonic to transonic flow regimes have been simulated to investigate Reynolds number, the angle of attack and Mach number effects on the Tollmien-Schlichting and crossflow instabilities. The simulated transition locations and pressure coefficient distributions agree well with available experimental data and demonstrate the effectiveness of the transition prediction tool.
