Linear and nonlinear models in wind resource assessment and wind turbine micro-siting in complex terrain
TL;DR: In this paper, the authors compare conventional techniques, such as linear models and cup anemometers, with flow simulation by computational fluid dynamics techniques (nonlinear models) and measurements by sonic anemometer, and discuss their relative merits in the characterisation of the wind over a coastal region.

A CFD based combustion model of an entrained flow biomass gasifier
TL;DR: In this article, a detailed Computational Fluid Dynamics (CFD) model is developed to simulate the flow and reaction in an entrained flow biomass gasifier, which can be used in gasifier design and analysis.
Journal ArticleDOI
The Turbulent Flows of Supercritical Fluids with Heat Transfer
TL;DR: In this article, the effects of buoyancy, flow acceleration, and significant variations in thermophysical properties have been found to be capable of describing the heat transfer degradation of supercritical fluids.

Analysis of an RNG based turbulence model for separated flows
Charles G. Speziale,S. Thangam +1 more
TL;DR: In this article, it was shown that the original version of the RNG K-epsilon model substantially underpredicts the reattachment point in the backstep problem.

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.
