Experimental Study of a High Speed Micro Waterwheel
Waterwheels are the oldest types of hydraulic machines. These turbines are of relatively simple design, large diameter, low rotational speed and high torques. But applying them as micro hydros of high speed and small diameter is yet to be explored. A micro hydro waterwheel of one meter diameter was designed and manufactured at the Iranian esearc†h Organization for Science and Technology (IROST...
متن کاملMicroscopic high-speed liquid-metal jets in vacuum
The operation of microscopic high-speed liquid-metal jets in vacuum has been investigated. We show that such jets may be produced with good stability and collimation at higher speeds than previously demonstrated, provided that the nozzle design is appropriate and that cavitation-induced instabilities are avoided. The experiments with a medium-speed tin jet (u 60 m/ s, Re=1.8·10, Z=2.9·10 ) show...
متن کاملHigh-Speed Penternary Inverter Gate Using GNRFET
This paper introduces a new design of penternary inverter gate based on graphene nanoribbon field effect transistor (GNRFET). The penternary logic is one of Multiple-valued logic (MVL) circuits which are the best substitute for binary logic because of its low power-delay product (PDP) resulting from reduced complexity of interconnects and chip area. GNRFET is preferred over Si-MOSFET for circui...
متن کاملEmergency power source for an ion vacuum pump.
This note describes a simple high-voltage dc generator which serves as an emergency power source for an ion vacuum pump during power interruptions, or failure of the main supply.
متن کاملA Very High Head Pump
Preliminary process design in 1997 for a new grass roots polymer unit in the Gulf Coast raised the possibility of using a single centrifugal pump instead of two reciprocating compressors to feed ethylene into the reactors. The objectives of this change were lower capital cost, energy consumption, and maintenance expense. Discussion of the possible application led finally to the design, manufact...
