Abstract

The invention discloses a turbulence field updating method. The method comprises the steps of obtaining sample turbulence data; carrying out model training by utilizing the sample turbulence data to obtain a reinforcement learning turbulence model; calculating to obtain initial turbulence data of the turbulence field through an RANS equation; processing the initial turbulence data through the reinforcement learning turbulence model to obtain predicted Reynolds stress; calculating the predicted Reynolds stress through the RANS equation to obtain updated turbulence data; according to the turbulence field updating method, the calculation precision can be effectively improved, and more accurate turbulence field updating is realized. The invention further discloses a turbulence field updating device and equipment and a computer readable storage medium, which all have the above beneficial effects.

Description

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