Pressure Reducing Valve Characterization for Pipe System Management

Procedia Engineering, 2016
AbstractPressure control strategy through Pressure Reducing Valves (PRVs) has been deeply investigated as management strategy, aimed at water leakage reduction avoiding very expensive pipe replacement programmes. On the contrary, few experimental data are available in literature, particularly in unsteady-state conditions.

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Capacity Testing and Local Flow Analysis of a Geometrically Complex Trim Installed within a Commercial Control Valve [PDF]

Industrial control valves often handle flows with very high pressure drops (conditions often referred to as severe service). In order to cope with such pressure drops, geometrically complex valve trims with many stages of pressure drops, are designed to ...
