Design and Performance Prediction of an Air Chamber for Reduction of Water Hammering

수충격 완화용 공기 챔버의 설계 및 성능 예측에 관한 연구

A computer program was developed for the prediction of transient flow in a water supply system. where an air chamber is installed to reduce the water hammering. The governing equations based on a characteristic method are solved using a finite difference method. A design process of an air chamber is shown in the present paper considering the effects of the initial air volume and the discharge coefficients of the orifice on the total volume and over-all performance of the chamber.
