This study develops thermofluidic pump technology that is powered by heat, rather than by electrical or mechanical power. The objective is to improve the performance of heat-recovery by Organic Rankine Cycles, by using a recently-proposed thermofluidic pump. The thermofluidic pump promises low-cost, high-reliability, and, since it does not consume any of the power produced by the expander, impr...

In order to study the transient characteristics of submersible tubular pump in process power failure, 6DOF model was used carry out three unsteady numerical values for whole flow channel pump. The results show that calculation based on fourth-order multi-point Adams–Moulton formula are better agreement with experimental than first-order format predict impeller motion. When unit is powered off, ...

The interaction between the rotor and stator is a major source of high amplitude pressure fluctuation flow-induced vibration in multistage centrifugal pumps. detrimental to reliable operation sensitivity severe if number stages more. In present experimental study, vertical submersible pump used measure level at Best Efficiency Points (BEP) determine influence stage operating speed on fluctuatio...

Deep geothermal energy systems employ electric submersible pumps (ESPs) in order to lift geothermal fluid from the production well to the surface. However, rough downhole conditions and high flow rates impose heavy strain on the components, leading to frequent failures of the pump system. As downhole sensor data is limited and often unrealible, a detailed and dynamical model system will serve a...
