EXPERIMENTAL STUDY OF LIQUID DISPERSION IN BUBBLE COLUMN
Diyala Journal of Engineering Sciences, 2008 The main object of this study is to investigate the influence of column diameter and superficial gas velocity on liquid phase dispersion coefficients (axial and radial dispersion coefficients), mixing times, gas holdup, and bubble dynamics (bubble ...

JGE, 2020 In the hydrocarbon exploration, we need the method that result the direct hydrocarbon indicator to estimate the reservoir location and dimension accurately. It is a difficult and long standing problem.

A CLEAR AGE–VELOCITY DISPERSION CORRELATION IN ANDROMEDA’S STELLAR DISK [PDF]
, 2015 The stellar kinematics of galactic disks are key to constraining disk formation and evolution processes. In this paper, for the first time, we measure the stellar age–velocity dispersion correlation in the inner 20 kpc (∼3.5 disk scale lengths) of M31 ...

Realizing normal group-velocity dispersion in free space via angular dispersion [PDF]
, 2021 It has long been thought that normal group-velocity dispersion (GVD) cannot be produced in free space via angular dispersion. Indeed, conventional diffractive or dispersive components such as gratings or prisms produce only anomalous GVD. We identify the conditions that must be fulfilled by the angular dispersion introduced into a plane-wave pulse to ...

STELLAR VELOCITY DISPERSION AND ANISOTROPY OF THE MILKY WAY INNER HALO [PDF]
, 2015 We measure the three components of velocity dispersion, σR, σθ, σϕ, for stars within 6 < R < 30 kpc of the Milky Way using a new radial velocity sample from the MMT telescope. We combine our measurements with previously published data so that we can more

Velocity Dispersion of Ionized Gas and Multiple Supernova Explosions
Open Astronomy, 2015 We use 3D numerical simulations to study the evolution of the Hα intensity and velocity dispersion for single and multiple supernova (SN) explosions. We find that the IHα– σ diagram obtained for simulated gas flows is similar in shape to that observed in

Resolved gas kinematics in a sample of low-redshift high star-formation rate galaxies [PDF]
, 2016 We have used integral field spectroscopy of a sample of six nearby (z~0.01-0.04) high star-formation rate (SFR~10-40 solar masses per year) galaxies to investigate the relationship between local velocity dispersion and star formation rate on sub-galactic scales.

Tracing Dark Matter Halos with Satellite Kinematics and the Central Stellar Velocity Dispersion of Galaxies [PDF]
, 2020 It has been suggested that the central stellar velocity dispersion of galaxies can trace dark matter halo mass directly. We test this hypothesis using a complete spectroscopic sample of isolated galaxies surrounded by faint satellite galaxies from the Sloan Digital Sky Survey Data Release 12.

Self‐Similarity and the Pair Velocity Dispersion [PDF]
The Astrophysical Journal, 1997 We have considered linear two point correlations of the form $1/{x^ }$ which are known to have a self-similar behaviour in a $ =1$ universe. We investigate under what conditions the non-linear corrections, calculated using the Zel'dovich approximation, have the same self-similar behaviour.
