Prediction of turbulent thermal convection in concentric and eccentric horizontal annuli

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.

Characterization of fluid dynamics and mass-transfer in an electrochemical oxidation cell by experimental and CFD studies

TL;DR: In this article, the authors investigated the mass transfer in a commercial electrochemical flow cell (DiaCell®) using computational fluid dynamics (CFD) simulations and validated by experimental measurements.

Computation of turbulent natural convection in rectangular enclosures with an algebraic flux model

TL;DR: In this article, the authors report on the computation of laminar and turbulent natural convection in rectangular enclosures with aspect ratios of 1 and 5 with simple-and mixed-boundary conditions in the range of Ra numbers from 104 to 1012.

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

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

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

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.
