Influence of VOF technique, turbulence model and discretization scheme on the numerical simulation of the non-aerated, skimming flow in stepped spillways
Arnau Bayón,Juan Pablo Toro,Juan Pablo Toro,Fabián A. Bombardelli,Jorge Matos,Petra Amparo López-Jiménez +5 more
TL;DR: In this paper, numerical models of the flow in the non-aerated region of stepped spillways have been developed using diverse turbulence closures and discretization schemes implemented in two CFD codes: OpenFOAM and FLOW-3D®.
Journal ArticleDOI
A critical evaluation of near-wall two-equation models against direct numerical simulation data
A. Sarkar,Ronald M. C. So +1 more
TL;DR: In this article, the authors compared 10 two-equation turbulence models with near-wall corrections by applying them to calculate plane Couette flow and found that the asymptotically consistent k-τ and k-ω models performed the best compared to direct numerical simulation data and experimental measurements.
Dissertation
Studies of turbulent boundary layer flow throughdirect numerical simulation
TL;DR: In this paper, a large effort has been put into the optimization of the numerical code on various super computers and the results from the simulations have confirmed the theoretical part of this work.

Turbulence modelling of low Reynolds number flow effects around a vertical axis turbine at a range of tip-speed ratios
TL;DR: In this article, a two-dimensional numerical investigation of a vertical axis turbine with focus on the prediction from two different turbulence modelling schemes is presented, and results are obtained as obtained from the original SST model and a modified version for low Reynolds number effects, recently tested by Wang et al. (2010).
Journal ArticleDOI
Modelling of a single confined turbulent slot jet impingement using various k — ϵ turbulence models
TL;DR: In this paper, a control-volume-based finite-difference method was used to solve the governing mass, momentum, turbulent energy, turbulent kinetic energy dissipation rate, and energy equations iteratively.

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.
