降阶近似反褶积模型的分析及其Navier-Stokes-Voigt正则化解释

Analysis of a Reduced-Order Approximate Deconvolution Model and its interpretation as a Navier-Stokes-Voigt regularization

L. C. Berselli, T. -Y. Kim, L. G. Rebholz

摘要:

我们研究了一个家庭最近推出的,降阶近似反卷积模型的数学和物理性质。首先,我们展示了这些模型和NS-Voigt模型之间的联系,并且NS-Voigt可以在近似反卷积框架中重新推导。然后,我们研究的能量平衡和光谱的模型,并提供一些湍流计算的结果,支持理论。还提供了模型的全局吸引子的分析,是一个详细的分析Voigt模型的脉动流的治疗。

英文摘要:

We study mathematical and physical properties of a family of recently introduced, reduced-order approximate deconvolution models. We first show a connection between these models and the NS-Voigt model, and that NS-Voigt can be re-derived in the approximate deconvolution framework. We then study the energy balance and spectra of the model, and provide results of some turbulent flow computations that backs up the theory. Analysis of global attractors for the model is also provided, as is a detailed analysis of the Voigt model's treatment of pulsatile flow.
