| description | Ball valve is the core control component for flow in HVAC (Heating, Ventilation and Air Conditioning) system. And valve's flow noise is one of the key parameters to evaluate its performance. Ball valve's flow field is modeled by finite element method based on Lighthill acoustic theory. And turbulent kinetic energy of the flow field is obtained. The noise generation mechanism of ball valve's flow is obtained by analyzing the contours of pressure, velocity and sound pressure level. In order to reduce sound pressure level of ball valve, noise reduction scheme was proposed. And ball valve was reformed. Flow field characteristics of the modified ball valve are analyzed by numerical simulation method. The feasibility of noise reduction scheme is verified by experiments. The results show that refitted ball valve has good noise reduction effect while guaranteeing small change of flow. |
