在本文中，我们开发了一个近似的计算框架，用于模拟与复杂的涡流系统在一个多元素的高升力翼型系统的襟翼侧边缘处看到的脉动流场。这些模拟的最终目标是提供这些波动的频谱内容的估计，以便可以估计由这种流场产生的噪声的频谱。利用这个计算框架的模拟结果显示。
In this paper we develop an approximate computational framework for simulation of the fluctuating flowfield associated with the complex vortex system seen at the side edge of a flap in a multi-element high-lift airfoil system. The eventual goal of these simulations is to provide an estimate of the spectral content of these fluctuations, in order that the spectrum of the noise generated by such flowflelds may be estimated. Results from simulations utilizing this computational framework are shown.
