摘要:

介绍了一类基于高斯过程随机函数族的计算流体动力学高阶方法。我们的方法是使用基于核的GP预测方法来插值/重建高阶近似求解双曲偏微分方程。我们提出的GP方法作为一种新的制定高阶(磁)流体动力学状态变量插值,替代传统的多项式为基础的方法。

英文摘要:

We introduce an entirely new class of high-order methods for computational fluid dynamics (CFD) based on the Gaussian Process (GP) family of stochastic functions. Our approach is to use kernel-based GP prediction methods to interpolate/reconstruct high-order approximations for solving hyperbolic PDEs. We present the GP approach as a new formulation of high-order (magneto)hydrodynamic state variable interpolation that furnishes an alternative to conventional polynomial-based approaches.
