Droplet activation, separation, and compositional analysis: laboratory studies and atmospheric measurements [PDF]
Atmospheric Measurement Techniques, 2011 Droplets produced in a cloud condensation nuclei chamber (CCNC) as a function of supersaturation have been separated from unactivated aerosol particles using counterflow virtual impaction.

Experimental study of pedestrian counterflow in a corridor [PDF]
, 2006 In this work the results of a pedestrian counterflow experiment in a corridor of a width of 2 meter are presented. 67 participants were divided into two groups with varying relative and absolute size and walked in opposite direction through a corridor ...

Aerodynamics of axisymmetric counterflowing jets [PDF]
Combustion and Flame, 2017 The laminar flow resulting from impingement of two steadily fed low-Mach-number gaseous jets issu- ing into a stagnant atmosphere from coaxial cylindrical ducts at moderately large Reynolds numbers,often used in combustion experiments, is studied through numerical integrations of the Navier-Stokes equations.

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017 The exact solution of the definition of convective motions in a layered large-scale flows of a viscous incompressible fluid in a steady case is considered. It was shown that the received problem is, firstly, overdetermined and, secondly, a nonlinear (due

Experimental Investigation of the Flow Resistance Characteristics of Air Vertically Flowing through a Horizontal Tube Bundle with Falling Film Water [PDF]
Journal of Applied Fluid MechanicsThe pressure drops and the friction factor of the air flowing up and down through a horizontal tube bundle with falling film water are investigated in this work, and the effects of air velocity, water spray density and air flow direction are studied. The

Influence of speed distribution in a rounded flow on the character of slopes erosion
RUDN Journal of Engineering Research, 2019 One of the most important issues of river hydraulics is the movement of water and the formation of a channel in a stream that has a non-straight-line outline in the plan. Under natural conditions for rivers characteristic winding shape in the plan.

Batch counterflow reverse osmosis
Desalination, 2021 Abstract High salinity waters (>7 wt%) remain a dominant challenge for reverse osmosis desalination, as the required osmotic pressures can exceed the burst pressure of the membranes. Osmotically assisted processes have been designed to circumvent this challenge, but have reduced efficiencies and extensive requirements for specialty pumps, stages and ...

Noise correlations of one-dimensional Bose mixtures in optical lattices
, 2010 We study the noise correlations of one-dimensional binary Bose mixtures, as a probe of their quantum phases. In previous work, we found a rich structure of many-body phases in such mixtures, such as paired and counterflow superfluidity.

Influence of tunnel slope on movement characteristics of thermal smoke in a moving subway train fire
Case Studies in Thermal Engineering, 2021 In this study, the three-dimensional unsteady Navier-Stokes equation and fully buoyant corrected Renormalization-group (RNG) k-ε turbulence model were employed to investigate the influence of tunnel slopes on the temperature distribution characteristics ...
