Liquid Turbulence Effect
"... A new approach to account for finite thermal conductivity and turbulence effects within atomizing droplets of an evaporating spray is presented in this paper. The model is an extension of the T-blob and T-TAB atomizatiodspray model of Trinh and Chen [9]. This finite conductivity model is based on th ..."

Turbulence effects in planetesimal formation
- ASTRONOMY AND ASTROPHYSICS
, 1998
"... The formation of planetesimals is investigated by studying the transport of dust particles in a local threedimensional simulation of accretion disc turbulence. Heavy particles fall rapidly towards the midplane, whereas lighter particles are strongly advected by the flow. For light particles the tur ..."

the turbulence leads to a rapid redistribution of particles such that their density per unit mass is approximately constant with height. There is no pronounced concentration of particles in vortices or anticyclones, as was suggested previously. This is partly because of the adverse effect of keplerian shear
MHD-TURBULENCE AND TURBULENT EFFECTS IN LARGE-SCALE DYNAMO
"... The lecture gives a short review on recent developments in the MHD-dynamo problem, including theory, observations, numerical modeling and experiments. Some contributions are presented in more details. Dynamo-effect is still the most intriguing problem of the fundamental magneto-hydrodynamics which i ..."

Modeling a turbulence effect in formation of the Antarctic Circumpolar Current
"... Abstract. A simple model to determine a turbulence effect in formation of the Antarctic Circumpolar Current (ACC) is suggested. The model is founded on the theory of rotationally anisotropic turbulence and is set up as a generalization of the geostrophic description of the Antarctic Circumpolar Curr ..."

Open Access Modelling Turbulence Effect in Formation of Zonal Winds
"... Abstract: A turbulence-affected mechanism of formation of zonal winds in the Earth’s troposphere is discussed from the perspective of the theory of rotationally anisotropic turbulence (the RAT theory). The turbulence effect is explained as an action of the turbulence rotational viscosity introduced ..."

Turbulent Effects on Fluid Flow through Disordered Porous Media
, 2001
"... The influence of turbulent effects on a fluid flow through a (pseudo) porous media is studied by numerically solving the set of Reynolds-averaged Navier-Stokes equations with the κ-ǫ model for turbulence. The spatial domains are two-dimensional rectangular grids with different porosities obtained by ..."

D.G.: High free stream turbulence effects on turbulent boundary layers
- J. Fluid Eng
, 1996
"... freestream turbulence levels significantly alter the characteristics of turbulent boundary layers. Numerous studies have been conducted with freestreams having turbulence levels of 7 percent or less, but studies using turbulence levels greater than 10 percent have been essentially limited to the eff ..."

to the effects on wall shear stress and heat transfer. This paper presents measurements of the boundary layer statistics for the interaction between a turbulent boundary layer and a freestream with turbulence levels ranging from 10 to 20 percent. The boundary layer statistics reported in this paper include mean
High Freestream Turbulence Effects in the Endwall Leading Edge Region,”
- ASME J. Turbomach.,
, 2000
"... ABSTRACT High freestream turbulence along a gas turbine airfoil and strong secondary flows along the endwall have both been reported to significantly increase convective heat transfer. This study superimposes high freestream turbulence on the naturally occurring secondary flow vortices to determine ..."

to determine the effects on the flowfield and the endwall convective heat transfer. Measured flowfield and heat transfer data were compared between low freestream turbulence levels (0.6%) and combustor simulated turbulence levels (19.5%) that were generated using an active grid. These experiments were
FREE-STREAM TURBULENCE EFFECTS ON FILM COOLING WITH SHAPED HOLES
"... ABSTRACT A comprehensive set of generic experiments has been conducted to investigate the effect of elevated free-stream turbulence on film cooling performance of shaped holes. A row of three cylindrical holes as a reference case, and two rows of holes with expanded exits, a fanshaped (expanded in ..."

In the conventional atmospheric turbulence numerical simulation techniques based on the “split”-operator method, the turbulence-induced refractive index inhomogeneities are represented by a set of infinitely narrow (2D) phase distorting layers (phase screens). These conventional phase screens cannot ..."
