Prediction of turbulent thermal convection in concentric and eccentric horizontal annuli
Sasa Kenjeres,K. Hanjalić +1 more
TL;DR: In this article, the application of the algebraic model for the turbulent heat flux Φu i, derived from the differential transport equation and closed with the low-Reynolds number form of transport equations for the kinetic energy k, its dissipation rate e, and temperature variance Φ 2 reproduced well the experimental data for mean and turbulence properties and heat transfer over a range of Rayleigh numbers, for different overheatings and inner-to-outer diameter ratios.

Large Eddy Simulation of Separated Flow over a Two-dimensional Hump with and without Control by Means of a Synthetic Slot-jet
TL;DR: In this paper, large eddy simulations for two flows separating from a two-dimensional hump in a duct are reported and discussed, where the flows differ through the presence or absence of a synthetic slot-jet injected in a sinusoidal manner, i.e. at zero net mass-flow rate, close to the location of separation and intended to reduce the extent of the separated region.

Low Reynolds number mixed convection in vertical tubes with uniform wall heat flux
TL;DR: In this paper, a correlation expressing the fully developed Nusselt number in terms of the Grashof and Reynolds numbers is proposed, which is valid for laminar and turbulent flows in the range 1000⩽ Re ⩽1500, Gr ⩾5×10 7.

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.
