Turbulence Modeling of Torsional Couette Flows
Sofia Haddadi,Sébastien Poncet +1 more
TL;DR: Poncet et al. as mentioned in this paper considered the numerical modeling of the turbulent flow inside a rotor-stator cavity subjected or not to a superimposed throughflow and provided a detailed mapping of the hydrodynamic flow over a wide range of rotational Reynolds numbers.

A wall-distance-free low Re k — ϵ turbulence model
U. Goldberg,D. Apsley +1 more
TL;DR: In this paper, a low Reynolds number k − ϵ turbulence model is presented based on the following three attributes: (1) it involves neither explicit wall distance nor normal-to-wall directionality, except to the first grid point off walls; (2) it enforces time scale realisability; (3) invokes a simple wall boundary condition for ϵ Several computed results are shown, indicating the validity of the current approach.

Turbulence modeling effects on the CFD predictions of flow over a NASCAR Gen 6 racecar
TL;DR: In this article, a full-scale NASCAR Gen 6 Cup car was simulated using three commonly used eddy viscosity turbulence models, viz. the realizable and AKN k − e, and SST k − ω.

Present Status of Second-Order Closure Turbulence Models. I: Overview
S. Y. Jaw,C. J. Chen +1 more
TL;DR: An overview of the second-order closure turbulence models is presented in this paper, where the authors compare the applicability of the existing turbulence models, modifying or even remodeling, the e equation, the dissipation rate of turbulent kinetic energy, and pressure-strain terms of the Reynolds stress, \Iū\dīū\dj¯\N, equations is necessary.

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.
