Modelling Analysis of Oxygen Transport During Czochralski Growth of Silicon Crystals
TL;DR: In this paper, a coupled two-dimensional stationary modeling of global heat transfer, laminar flow of inert gas and turbulent flow in Si melt, and transport of dissolved oxygen in the melt and SiO vapor in the gas is proposed.

Evaluation of turbulence models for estimating the wake region of artificial reefs using particle image velocimetry and computational fluid dynamics
Dongha Kim,Somi Jung,Won-Bae Na +2 more
TL;DR: In this paper, the authors compared five turbulence models and verified the CFD results using particle image velocimetry (PIV) and found that the RSM optimally predicted the overall characteristics of the wake region.

Sensitivity-based analysis of the k–ε model for the turbulent flow between two plates
André Bardow,Christian Bischof,H. Martin Bücker,Georg F. Dietze,Reinhold Kneer,Ansgar Leefken,Wolfgang Marquardt,Ulrich Renz,Emil Slusanschi +8 more
TL;DR: In this article, the impact of model parameters on the practical relevance of models in different classes of application scenarios is not fully understood, and a systematic approach for assessing parameter impact involves optimization methods for computational fluid dynamics that allow for quantitative model analysis by rigorous comparison with experimental data, in order to illustrate this systematic approach, the k-e turbulence model is analyzed on the basis of laser Doppler velocimetry measurements for the flow between two plates.

Swirling gas–solid flow through pneumatic conveying dryer
TL;DR: In this article, the Eulerian-Lagrangian model is used to simulate the two-phases of a swirling pneumatic conveying dryer and the model takes into account the lift and drag forces and the effect of particle rotation as well as the particles dispersion by turbulence effect.

The prediction of laminarization with a two-equation model of turbulence
W.P. Jones,Brian Launder +1 more
TL;DR: In this article, the local turbulent viscosity is determined from the solution of transport equations for the turbulence kinetic energy and the energy dissipation rate, and the predicted hydrodynamic and heat-transfer development of the boundary layers is in close agreement with the measured behaviour.

The calculation of low-Reynolds-number phenomena with a two-equation model of turbulence
W.P. Jones,Brian Launder +1 more
TL;DR: In this article, the authors present numerical predictions of various turbulent shear flows in which the structure of the viscous sublayer exerts appreciable influence on the flow, where the turbulence energy and its dissipation rate are calculated by way of transport equations which are solved simultaneously with the conservation equations for the mean flow.

Heat and mass transfer from rotating cones
C. L. Tien,D. T. Campbell +1 more
TL;DR: In this article, heat transfer by convection from isothermal rotating cones is investigated experimentally by measuring the sublimation rate from naphthalene-coated cones and using the analogy between heat and mass transfer.
