Research on the Effect of Orifice Plate Parameters on Reducing Airflow Pulsation in Piping System

The addition of orifice plate near the large container is an effective method to reduce airflow pulsation in the pipeline. It has been widely used in industrial production and has achieved good results. The air flow pulsation takes place regularly in the long-distance gas pipeline, no large container or near large container should not be added the orifice. Therefore, this paper is to study the effect of adding orifice plate on the suppression of airflow pulsation. And it simulates the fluid pressure distribution with CFX, studies the effect of the installation position and the aperture ratio on the airflow pulsation in the pipeline under different working conditions. The results show that, according to the pipeline of the working conditions and the pressure loss, an orifice plate of small aperture ratio should be installed away from the constant pressure position, which has achieved the best suppression effect.
