Application Status and Development Trend of Computational Fluid Dynamics in Agricultural Engineering.

Computational fluid dynamics (CFD) is a method for systematic analysis based on computer numerical calculation and image display. It is often used to analyze the flow mechanisms of gas-solid and gas-liquid two-phase flow in agricultural equipment. It is a new method for digital design of agricultural equipment, which has good application prospects. The commonly used calculation models of CFD in simulating agricultural materials and its application in agricultural equipment were summarized. Combined with the application of agricultural engineering, the future development trend of CFD was proposed on how to adapt to the future development needs of agricultural engineering. The results indicated that, due to the complex types of operation objects and easy damage of agricultural equipment, it was necessary to fully consider the physical characteristics of the operation objects and the relationship among components. The multidisciplinary coupling analysis, fine modeling and real-time prediction of high fidelity simulation would be the future development trend of CFD. [ABSTRACT FROM AUTHOR]
