Disentangling Spatial and Flow Anisotropy
نویسنده
چکیده
Two generalisations of the blast-wave model to non-central nuclear collisions are constructed, and elliptic flow as well as azimuthal dependence of correlation radii are calculated. Particular attention is paid to how different azimuthal dependences of transverse flow direction can cause qualitatively different anisotropic fireballs to give same v2 as a function of the transverse momentum. The simultaneous dependence of v2 and the oscillation of correlation radii on both spatial and flow anisotropy is studied in great detail.

An Azimuthally Anisotropic Blast-wave Model
Abstract. I investigate the correlation between spatial and flow anisotropy in determining the elliptic flow and azimuthal dependence of the HBT correlation radii in non-central nuclear collisions. It is shown that the correlation radii are in most cases dominantly sensitive to the anisotropy in space. In case of v2, the correlation depends strongly on particle species. A procedure for disentan...
متن کاملDisentangling inertial waves from eddy turbulence in a forced rotating-turbulence experiment.
We present a spatiotemporal analysis of a statistically stationary rotating-turbulence experiment, aiming to extract a signature of inertial waves and to determine the scales and frequencies at which they can be detected. The analysis uses two-point spatial correlations of the temporal Fourier transform of velocity fields obtained from time-resolved stereoscopic particle image velocimetry measu...
متن کاملThe Effect of Spatial Variability and Anisotropy of Soils on Bearing Capacity of Shallow Foundations
Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...
متن کاملStochastic Analysis of Seepage through Natural Alluvial Deposits Considering Mechanical Anisotropy
The soil is a heterogeneous and anisotropic medium. Hydraulic conductivity, an intrinsic property of natural alluvial deposits varies both deterministically and randomly in space and has different values in various directions. In the present study, the permeability of natural deposits and its influence on the seepage flow through a natural alluvial deposit is studied. The 2D Finite Difference c...
متن کاملSpatial detection of ferromagnetic wires using GMR sensor and based on shape induced anisotropy
The purpose of this paper is to introduce a new technique for row spacing measurement in a wire array using giant magnetoresistive (GMR) sensor. The self-rectifying property of the GMR-based probes leads to accurately detection of the magnetic field fluctuations caused by surface-breaking cracks in conductive materials, shape-induced magnetic anisotropy, etc. The ability to manufacture probes h...
