摘要

摘要: 近年来，基于RANS环境下引入预测转捩过程的模型越来越受到各国学者的关注．Langtry于2006年提出了一种基于当地变量进行转捩判据的模型，但这个转捩模型有两个核心的经验关系式直到2009年才公开．该文在对转捩模型机理进行分析理解的同时，通过对低速平板表面摩擦因数模拟试验的校核，提出了一套基于来流湍流度修正的经验关系式．并针对高超声速转捩问题对转捩动量厚度开始修正式进行了改进，最后通过对低速、跨音速翼型和高Ma双楔平板的计算，证明这一套经验关系式的可靠性与实用性．

Abstract: Recently, introducing a transition predicting model in to RANS environment was paidore and more attention to. Langtry proposed a correlation-based transition model in 2006,which was built strictly on local variables. However, two core correlations had not been pubished by the originator of the model until 2009. The mechanism of this transition model was anlyzed and discussed, after a series of numerical validations in skin friction coefficien to fflatlate boundary layers, a new correlation based on freestream turbulence in ten sity was developed, and the empirical correlation of transition onset momentum thickness Reynold number aiming at the hyperson ic transition was miproved. Finally, low-speed/transonic airfoil and a hypersonic double wedge flatare tested to prove the reliability and practicab ility of this correlation.
