作为随机偏微分方程极限的二维Smagorinsky型大涡模式
2D Smagorinsky type large eddy models as limits of stochastic PDEs
摘要:
我们证明了一个版本的Smagorinsky大涡模型的涡量形式的二维流体是合适的随机模型的大尺度,其中小湍流涡的影响是由运输型噪声模拟的缩放限制。
英文摘要:
We prove that a version of Smagorinsky Large Eddy model for a 2D fluid in vorticity form is the scaling limit of suitable stochastic models for large scales, where the influence of small turbulent eddies is modeled by a transport type noise.
