We use a simple a transverse radial boost scenario coupled to PYTHIA events to illustrate the impact radial flow may have on twoand three-particle correlation functions measured in heavy-ion collisions. We show that modest radial velocities can impart strong modifications to the correlation functions, some of which may be interpreted as same side ridge and away side structure that can mimic con...

In this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. We study a two-dimensional advective accretion disc in the presence of thermal conduction. We find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. We show that the global structure of an advec...

Due to high applicability of the fixed bed catalytic naphtha reforming reactors, hydrodynamic features of this kind of reactors with radial flow pattern are improved in this work by utilising computational fluid dynamics technique. Effects of catalytic bed porosity, inlet flow rate and flow regime through the bed on the flow distribution within the system are investigated.It is found that t...

Background Radial sampling is often used in dynamic CMR because it is robust to flow and motion, supports short echo times, and provides a diffuse aliasing pattern. One drawback is that current implementations do not support anisotropic field-of-view (FOV). Larson et al. [1] previously provided a simple scheme for supporting anisotropic FOV in static radial imaging. We extend the approach to go...

Light experiences a non-uniformly moving medium as an effective gravitational field, endowed with an effective metric tensor g̃μν = η μν + (n2 − 1)uμuν , n being the refractive index and uμ the fourvelocity of the medium. Leonhardt and Piwnicki [Phys. Rev. A 60, 4301 (1999)] argued that a flowing dielectric fluid of this kind can be used to generate an ’optical black hole’. In the Leonhardt-Piwn...

When heavy ions collide at ultra-relativistic energy, thousands of particles are emitted and it is reasonable to attempt to use hydrodynamic descriptions, with suitable initial conditions, to describe the time evolution of the collisons. In the longitudinal direction pions seem to exhibit Landau flow. This simple model assumes that all the entropy in the collisions is created the instant the tw...

“Plasma hole” is a singular vortex spontaneously formed in an electron cyclotron resonance plasma. So far the ion flow velocity field associated with the plasma hole has been measured with a directional Langmuir probe (DLP). Here we present the first result of measuring azimuthal and radial flow velocity profiles of the plasma hole in an argon plasma using a laser induced fluorescence (LIF) Dop...
