In recent years the heat fluxes that must be removed from terrestrial electrical systems have been steadily increasing. The same increase in electrical component heat flux can also be seen in satellite and aerospace applications. As a result, it has proven necessary to develop heat pump systems that can operate in low-gravity environments with high reliability and efficiency to cool electrical ...

A teaching machine that simulates intravascular conditions found during a human therapeutic embolization has been constructed. A submersible pump drives fluid through a circuit of tubing. One limb of a Y (a vascular bifurcation) located in this circuit leads to a model arteriovenous malformation. Catheters placed in this limb may introduce embolic materials by various techniques, and those tech...

A Moving Horizon Estimator (MHE) is designed for a petroleum production well with an Electric Submersible Pump (ESP) installed for artificial lift. The focus is on estimating the flow rate from the well, the viscosity of the produced fluid, and the productivity index of the well. The software package ACADO is used to implement a Moving Horizon Estimator using a third-order nonlinear model. Simu...

Water is an essential element of life. The government of Ethiopia in collaboration with development allies’ attempts to increase pure water supply. Even though the coverage boosted dramatically still there is critical challenges in maximizing equipment’s reliability, improving service quality, maximizing capacity utilization, minimizing life cycle costs of water production mach...

This paper studies a superconducting maglev submersible cryogenic liquid pump (CLP) using magnetic bearing (SMB). A new structure is proposed for the self-stability of high-temperature levitation, and compact disk motor-pump. The rotor axial-flux motor connected with centrifugal impeller to form an impeller-rotor CLP. Supported by SMB system, rotates frictionlessly self-stabilisation as suspens...
