Small and micro hydropower systems represent an attractive solution for generating
electricity at low cost and with low environmental impact. The pump-as-turbine (PAT) …

Gerotor pumps, as well known, are widely used in lubrication circuits of internal combustion
engines for their simplicity, high efficiency and low costs. In this paper an experimental …

This paper compared the capabilities of the artificial neural network (ANN) and the fuzzy
logic (FL) approaches for recognizing and discriminating partial discharge (PD) fault …

This paper introduces an approach to study a valve's internal fluid dynamics. During
operation, the flow causes forces on the spool. These forces must be correctly balanced …

Globe valve is widely used in numerous industries, and its driving energy consumption
accounts for high percentages of the whole piping system. In order to figure out novel globe …

Cartridge valves are widely used in mobile applications, where they are screwed in
manifolds, to realize opportune circuit layouts. These valves are quite simple in operation …

The performance of spool valves can deteriorate and noise can occur due to cavitation. The
noise sound levels caused by cavitation are influenced by many parameters, among which …

Pilot-control globe valve (PCGV) can use the pressure drop caused by fluid flowing through
the orifice located at valve core bottom to open or close the main valve using a small pilot …

This paper proposes an effective methodology to decrease the unstable fluid load on the
plug of a poppet valve. The aim is to minimize the impact of the sudden fluid load on the …

The dynamic motion of tethered undersea kites (TUSK) is studied using numerical
simulations. TUSK systems consist of a rigid winged-shaped kite moving in an ocean …
