摘要
本文对后掠层流机翼可压缩边界层进行了计算研究。引入新的相似变换形式,避免了Kaups-Cebeci方法在变换中可能出现的奇性,导出了在新的相似变换下的偏微分方程组。对层流控制(LFC)和自然层流(NLF)机翼进行了计算,得到了满意的结果。
In this paper compressible boundary layers on swept laminar flow wings are investigated computationally. Different from the Kaups-Cebeci's method, a new form of similarity transformation, into which no singularity will be introduced;, is adopted. Partial differential equations are derived by using this new transformation. Examples for laminar-flow-control (LFC) and natural-laminar-flow (NLF) wings are calculated and useful results are obtained.
