跨音速自然层流翼型反设计研究
Inverse Design of the Transonic Natural Laminar Flow Airfoil
摘要
Abstract
The inverse design method was studied based on gappy proper orthogonal decomposition ( POD) . According to surface pressure distribution, the gappy POD reduced order model was used to re-construct missing data of an airfoil. In the initial snapshot sampling process, ΔCST was used to get the snapshot, then the basic airfoil was replaced by the inverse designed, and the new snapshot designed by POD was added to snapshot. For laminar flow airfoil inverse design, pressure distribution snapshot were got by γ-Reθtransition model. Two different pressure distributions of the transonic NLF airfoil were pro-posed. Then two transonic NLF airfoils could be obtained by the inverse design method. The ability for postponing the transition of different pressure distributions under different Reynolds number and Mach numbers were studied in detail.关键词
