Abstract

Slotted natural-laminar-flow airfoils are an enabling technology for development of ultra-efficient commercial aircraft. Design and analysis of vehicles using these airfoils requires tools for predicting flows with transitioning boundary layers. A prototype version of the HPCMP CREATE™-AV Kestrel finite-element CFD solver COFFE which contains a laminar-turbulent transition prediction capability via the amplification factor transport model is exercised on several baseline SNLF airfoil geometries, and preliminary results are presented.
