Detailed modeling of the effects of K/Na additives on the thermal DeNO(x) process
TL;DR: In this article, a reduced mechanism simplified from a detailed chemical kinetics mechanism containing N/H/O/K/Na elements was developed and validated in a CFD software, and the effect of potassium and sodium additives on the selective non-catalytic reduction (SNCR) thermal DeNO(x) process was simulated.
Theoretical investigation on the effect of fluid flow between the hull of a ship and ice floes on ice resistance in level ice
TL;DR: In this paper, the authors study the effect of the last two phenomena on ice resistance in the sliding phase and develop a calculation tool for this purpose, which can be used to calculate the flow in the gap between the hull surface and an ice floe.

Three-dimensional simulation of a simplified advanced gas-cooled reactor fuel element
Amir Keshmiri,Amir Keshmiri +1 more
TL;DR: In this paper, simulations of a simplified three-dimensional representation of the UK fleet of advanced gas-cooled reactors (AGRs) fuel element using a 30° sector configuration were carried out using the v 2 -f formulation which was shown to be one of the most accurate turbulence models in earlier simulations of two-dimensional rib-roughened channels.

The computation of flow and heat transfer through square‐ended U‐bends, using low‐Reynolds‐number models
TL;DR: In this article, the authors focused on the computation of turbulent flow and heat transfer in U-bends of strong curvature and showed that the mean flow development is mainly influenced by mean pressure rather than the turbulence field.
Journal ArticleDOI
Numerical modeling of free and submerged labyrinth weir flow for a large sidewall angle
TL;DR: In this paper, numerical simulations of free-flow and submerged labyrinth weirs were conducted for a large sidewall angle, using commercially available computational fluid dynamics software, for three different turbulence models.

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.
