Cfd Numerical Analysis

This paper performs CFD numerical analysis on the wind direction variation characteristics of the upper part of the platform under the running condition of the whole machine, and analyses whether the current location of the equipment is suitable for placing the wind direction measuring equipment and finding a better position in the area. The vicinity of the reference point is the area where the airflow is relatively intense, and the wind direction is complex and changeable. In-depth CFD research on this flow phenomenon can obtain an intuitive wind direction state and inherently subtle changes.

The hydraulic slide valve with round orifice spool is often used in hydraulic control system. But it is prone to rotate when the hydraulic oil flow is large. The three-dimensional fluid analysis technology was used to numerically simulate the flow field in the hydraulic slide valve. By using the pressure and velocity characteristics generated for different spool structures by the CFD numerical analysis, the main reason of slide valve rotation was analyzed, which can provide basis for the optimal design of the slide valve structure.
