We demonstrate an ion pump, consisting of a nanochannel with an AC driven asymmetric electrode array. Our system enables us to actively pump ions using a low driving voltage. In all experiments the electrical double layers are overlapping. Via viscous coupling ion pumping is accompanied by liquid pumping. Actuation below 500 mV at 10 Hz results in a liquid velocity of ~10 μm/s, corresponding to...

Ocean economy plays a crucial role in the strengthening maritime safety industry and in the welfare of human beings. Electric Submersible Pumps (ESP) have been widely used in floating platforms on the sea to provide oil for machines. However, the ESP fault may lead to ocean environment pollution, on the other hand, a timely fault diagnosis of ESP can improve the ocean economy. In order to meet ...

Oil pump in diesel engine has significant effect on energy consumption and environment pollution. In this paper, the modeling and simulation of a gear oil pump used in a diesel engine and its fluid flow analysis by a solver has been explained. Also the optimization and redesign of it has been discussed and then the outcomes have been compared with the experimental and previous results. The t...

The work consists of the development a market-friendly 600 W photovoltaic battery-less water pumping system. system is composed four 280 Wp solar panels, an auxiliary 10 panel, three-phase converter and ½ horsepower (hp) submersible pump. electronic stage involves resonant DC-DC in series with voltage source inverter. novelties this are related to use fixed duty-cycle frequency for application,...
