A compressed air vessel (CAV) has been tested under transient conditions to show its ability to absorb the pressure surges and to demonstrate the energy storage capability of the air pocket. Proper dimensionless parameters are introduced and the relationship between governing factors is analyzed. Smaller sizes of air pocket lead to higher pressures, and there exists a critical size associated with the higher pressure value depending on the flow velocity. air pocket, compressed air vessel, flow energy storage, water hammer © IWA Publishing 2016 You do not currently have access to this content.
