Short- and long-term prediction of a chaotic flow: A physics-constrained reservoir computing approach

no code implementations15 Feb 2021 Nguyen Anh Khoa Doan, Wolfgang Polifke, Luca Magri

We propose a physics-constrained machine learning method-based on reservoir computing- to time-accurately predict extreme events and long-term velocity statistics in a model of turbulent shear flow.
