Influences of Turbulence Characteristic on the Dispersion Behavior of Droplets in the Spray Flame
The authors investigated the effect of the turbulence of an air current on droplet dispersion in a spray flame. Wire meshes of different mesh sizes were inserted behind a two-fluid type nozzle each time to vary the air current turbulence characteristics,

Observation of aerosol particle capturing behavior near gas-liquid interface
An aerosol particle capturing by a gas-liquid interface has been applied in many industries. One example of this is the radioactive aerosol removal system in the safety system of the nuclear reactor such as filtered venting system.

Identification of a particle collision as a finite-time blowup in turbulence
We propose an Eulerian approach to investigate the motion of particles in turbulence under the assumption that the motion of particles remains smooth in space and time until a collision between particles occurs. When the first collision happens, particle

Scalable Block Preconditioners for Linearized Navier-Stokes Equations at High Reynolds Number
We review a number of preconditioners for the advection-diffusion operator and for the Schur complement matrix, which, in turn, constitute the building blocks for Constraint and Triangular Preconditioners to accelerate the iterative solution of the ...

A regime map for dry powder coating: the influence of material properties and process parameters
A numerical study is carried out to investigate the combined influence of material properties and process parameters on coating quality in a high shear mixer (specifically an FT4 Powder Rheometer) to construct a regime map.

Oseen's correction to stokes drag on axially symmetric arbitrary particle in transverse flow: A new approach [PDF]
In this paper, Oseen’s correction to Stokes drag experienced by axially symmetric particle placed in a uniform stream perpendicular to axis of symmetry(i.e. transverse flow) is obtained.

Efficiency of capture of inertia aerosol particles in a periodic cell with a porous cylinder
In this study, aerosol flow in circular and rectangular periodic cells of a regular row of porous cylinders is simulated. The hydrodynamic field of the carrier medium flow outside and in the domain of the porous cylinder is described in the approximation

About the use of the Stokes number for mathematical modeling of two-phase jet flows
The appropriateness of using the Stokes number as a single similitude parameter for representation of the results of research on two-phase jet flows in a criteria form was considered.
