在本文中,我们专注于降阶模型(ROM)闭包的数学基础。首先,我们将可验证性的概念从大涡模拟扩展到ROM设置。具体地说,我们称ROM闭包模型为可验证的,如果一个小的ROM闭包模型错误(即,真实ROM闭合和模型化ROM闭合之间的小差异)意味着小的ROM误差。其次,我们证明了这里研究的数据驱动ROM闭包(即,数据驱动的变分多尺度ROM)是可验证的。最后,我们研究了数据驱动的变分多尺度ROM在数值模拟一维Burgers方程和二维绕流圆柱在Reynolds数和。
In this paper, we focus on the mathematical foundations of reduced order model (ROM) closures. First, we extend the verifiability concept from large eddy simulation to the ROM setting. Specifically, we call a ROM closure model verifiable if a small ROM closure model error (i.e., a small difference between the true ROM closure and the modeled ROM closure) implies a small ROM error. Second, we prove that the data-driven ROM closure studied here (i.e., the data-driven variational multiscale ROM) is verifiable. Finally, we investigate the verifiability of the data-driven variational multiscale ROM in the numerical simulation of the one-dimensional Burgers equation and a two-dimensional flow past a circular cylinder at Reynolds numbersand.
