Description
technical field [0001] The present application relates to the technical field of reinforcement learning, in particular to a method for updating a turbulent flow field, and also to a device, device and computer-readable storage medium for updating a turbulent flow field. Background technique [0002] Turbulence phenomena commonly exist in nature and industry. For example, extreme weather such as sandstorms, typhoons and tsunamis in nature, the complex flow environment in which large civil airliners and passenger ships are located, and the internal flow of the engine involved in the independent research and development of aero-engines, etc. Typical turbulence phenomenon. Turbulence is a complex flow phenomenon with irregular spatial and temporal distribution, which is characterized by strong nonlinearity, randomness, and multi-scale. [0003] In the turbulent flow field, the Reynolds number of the actual turbulent environment often reaches Re~O(10 10 ), for such complex flow...
