The authors demonstrate the use of millisecond x-ray phase-contrast imaging for velocity measurement particle-laden flows in an optically opaque vessel. Taking advantage particle size polydispersity, this single-particle tracking approach is extremely effective on with tracer particles exhibiting a great distribution ranging from 1μm to hundreds micrometers, which impossible visible-light-based techniques. Furthermore, tomographic reconstruction was applied yield three-dimensional flow field...
Previous studies have found that the difference in combustion characteristics of gaseous and liquid kerosene injection supersonic combustor is sensitive to equivalent ratio. In this paper, previous work extended a high ratio gain deeper understanding effect states on performance via numerical computation. The simulation results match well with experiments demonstrate due different jet structures, cavity shear layer penetrates deeply into cavity, forming two recirculation zones therein. As...
We used ultrafast x radiography and developed a novel multiphase numerical simulation to reveal the origin unique dynamics of liquid-jet-generated shock waves their interactions with jets. Liquid-jet-generated are transiently correlated structural evolution disintegrating The revealed that aerodynamic interaction between liquid jet results in an intriguing ambient gas distribution vicinity front, as validated by x-radiography measurements. excellent agreement data suggests combined...
A search for physics beyond the Standard Model has been performed with high-Q^2 neutral current deep inelastic scattering events recorded ZEUS detector at HERA. Two data sets, e^+ p \to X and e^- X, respective integrated luminosities of 112 pb^-1 16 pb^-1, were analyzed. The reach Q^2 values as high 40000 GeV^2. No significant deviations from predictions observed. Limits derived on effective mass scale in eeqq contact interactions, ratio leptoquark to Yukawa coupling heavy models parameter...
X-ray radiography was used to measure the behavior of four fuel sprays from a light-duty common-rail diesel injector. The were at 250bar injection pressure and 1bar ambient pressure. Injection durations 400μs 1000μs tested, as axial single-hole nozzles with hydroground nonhydroground geometries. data provide quantitative measurements internal mass distribution spray, including near injector orifice. Such are not possible optical diagnostics. appear qualitatively similar. spray nozzle has...
The dispersion of monodisperse, inertial particles in a supersonic mixing layer consisting two sheared flows with differing pressures (P1 for the particle-laden jet flow and P2 airflow) is numerically investigated using large Eddy simulation Euler–Lagrange methods. calculations reveal following insights: pressure disparity between induces transverse gas effect, which swiftly deflects from high-pressure side to low-pressure side. growth rate increases ratio P2/P1 while deflected displacement...
