In this paper, the Eulerian–Lagrangian method and Tabakoff erosion model are used to study solid–liquid two-phase flow in a Francis turbine. Through analysis of overall pattern, particle flow, concentration, wear bladeless area unit under different guide vane openings, influence runner radial gap on surrounding field characteristics openings is revealed. The results show that smaller opening va...

This paper experimentally investigates a highly-loaded 1.5-stage transonic axial compressor, which comprises variable inlet guide vane, BLISK rotor, and stator in tandem arrangement. A detailed comparison between the newly designed compressor stage reference with conventional design was conducted by using extensive instrumentation. Thus, steady unsteady phenomena—focusing on aerodynamic aeroela...

During the last several years, a number of airborne and satellite hyperspectral sensors have been developed or improved for remote sensing applications (Green, 1988-2000; Vane et al., 1993; Kruse & Boardman, 1999). Imaging spectrometry allows the detection of materials, objects and regions in a particular scene with a high degree of accuracy. Hyperspectral data typically consist of hundreds of ...

We adress the problem of Fock space representations of (free) multiplet component fiels encountered in supersymmetric quantum field theory insisting on positivity and causality. We look in detail on the scalar and Majorana components of the chiral supersymmetric multiplet. Several Fock space representations are introduced. The last section contains a short application to the supersymmetric Epst...

Quite a few years ago, while studying the inactivation of bradykinin by kidney extracts, an enzyme in a particulate (microsomal) fraction of rat kidney was found to release the C-terminal dipeptide (Phe-Arg) of bradykinin (Erdos & Yang, 1967). This enzyme, named kininase 11, was solubilized with deoxycholate and partially purified by gel filtration. It was subsequently also isolated from human ...

Gas turbine engines have a high power-to-weight ratio, making them ideal for generation of aircraft thrust, and can have excellent electrical power generation efficiencies when used in a combined cycle power plant. A complex vortical flow at the junction of the nozzle guide vane airfoil and its casing (endwall) in the turbine section tends to decrease aerodynamic efficiency and increase metal t...
