RANS simulation of neutral atmospheric boundary layer flows over complex terrain by proper imposition of boundary conditions and modification on the k-ε model
TL;DR: In this article, a modelling methodology is proposed for RANS simulations of neutral ABL flows on the basis of the standard k-e model, which allows the adoption of an arbitrary shear stress model, and the results show that relatively good homogeneity can be achieved with this modelling methodology for various sets of inflow boundary profiles.
Journal ArticleDOI
Investigation of Anisotropy-Resolving Turbulence Models by Reference to Highly-Resolved LES Data for Separated Flow
TL;DR: The predictive properties of several non-linear eddy-viscosity models are investigated by reference to highly-resolved LES data obtained by the authors for an internal flow featuring massive separation from a curved surface as discussed by the authors.

Machine-learning based error prediction approach for coarse-grid Computational Fluid Dynamics (CG-CFD)
TL;DR: The proposed CG-CFD method has proven capable of correcting the coarse-grid results and obtaining reasonable predictions for new cases and shows potential for a good predictive capability.

Modeling the effects of a solid barrier on pollutant dispersion under various atmospheric stability conditions
TL;DR: In this article, the authors used the Comprehensive Turbulent Aerosol Dynamics and Gas Chemistry (CTAG) model to simulate the spatial gradients of SF6 concentrations behind a solid barrier under a variety of atmospheric stability conditions collected during the Near Road Tracer Study (NRTS08).

CFD modeling of heat transfer in turbulent pipe flows
TL;DR: In this paper, the Lai and So model was attributed to its success in the predictions of flow parameters such as mean axial velocity, turbulent kinetic energy, eddy diffusivity, and overall energy dissipation rate.

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.
