ABSTRACT

Turbulence is a common flow phenomenon in nature and engineering, characterized by irregularity and strong randomness. Turbulence calculation is critical in many engineering designs and applications. To explain the flow pattern of turbulence, scientists have created various models to simulate it. At present, the prediction of turbulence transition and the improvement of large eddy simulation are still not comprehensive, and there is a lack of systematic summary and reasonable research routes. Therefore, this article introduces the simulation ideas and basic control equations of three methods: Reynolds averaged, direct numerical simulation, and large eddy simulation. The development background, research status, and specific applications of large eddy simulation technology are emphasized. The advantages, disadvantages, and applicability of large eddy simulation are analyzed in depth. This article aims to review the development of turbulence models and summarize the current main turbulence models, providing a reference for related research and of great value for future research on large eddy simulation.
