متن کاملSimulation and Damage Analysis of an Accidental Jet Fire in a High-Pressure Compressed Pump Shelter
BACKGROUND As one of the most frequently occurring accidents in a chemical plant, a fire accident may occur at any place where transfer or handling of combustible materials is routinely performed. METHODS In particular, a jet fire incident in a chemical plant operated under high pressure may bring severe damage. To review this event numerically, Computational Fluid Dynamics methodology was us...
متن کاملAn electron jet pump: The Venturi effect of a Fermi liquid
A three-terminal device based upon a two-dimensional electron system is investigated in the regime of nonequilibrium transport. Excited electrons scatter with the cold Fermi sea and transfer energy and momentum to other electrons. A geometry analogous to a water jet pump is used to create a jet pump for electrons. Because of its phenomenological similarity we name the observed behavior the “ele...
متن کاملEffect of Tip Clearance on Hydraulic Performance of Water-jet Pump
The k-ω Shear Stress Transport (SST) turbulence model is adopted to study the hydrodynamic performance of the water-jet axial pump which is applied in Unmanned Surface Vehicle (USV). The numerical simulation of the whole passage of the water-jet pump is carried out for four different tip clearance with δ = 0.3 mm, δ = 0.8 mm, δ = 1 mm and δ = 1.4 mm. And the results, in term of external charact...
متن کاملImproving the Reliability of a Decoking Jet Pump Train with a Hydrodynamic Variable Speed Drive
Delayed coking is a refining process that consists of the upgrading of petroleum residues into lighter and more valuable hydrocarbon fractions by promoting thermal cracking on the residue stream. Petroleum coke is a by-product of this process and depending on its morphology it can be used as fuel for steam generation, cement calcination or as feed stock for the manufacturing of aluminum and ste...
