Abstract: A series of large-eddy simulators of free and sheared convective flow between moving flat plates is presented. Results for free convection are compared with laboratory data. The ratio of friction velocity to the convective ...

Abstract: Numerical calculations of two-dimensional convection between flat plates at high Rayleigh numbers are presented. They do not show the large cell aspect ratios observed by Rothermel and Agee in their numerical calculations ...

Abstract: A probabilistic framework for incorporating uncertainty in air quality models is described. The quantitative dependence of the uncertainty in calculated air quality concentrations on the uncertainty in the input meteorological ...

Abstract: A series of nearly instantaneous vertical cross sections of power-plant plume concentrations obtained by both airborne and ground-based lidar systems for the Electric Power Research Institute (EPRI) Plume Model Validation ...

Abstract: A two-dimensional numerical study of breaking Kelvin-Helmholtz billows is presented. The turbulent breaking process is modeled using second-order closure methods to describe the small-wale turbulence, while the large-scale ...

Abstract: Fractal analysis techniques have been applied to the concentration fields from large-eddy simulations of plume dispersion in a turbulent boundary layer. Fractal dimensions between 1.3 and 1.35 are obtained from area-perimeter ...

Abstract: The Gaussian puff model framework is extended to provide a description of velocity shear distortion effects. An efficient splitting-merging algorithm is presented so that a maximum puff size can be specified for a calculation. ...

Abstract: Two-dimensional numerical computations of the developing boundary layer with a positive surface heat flux are presented. The model incorporates moisture phase-change effects; we are particularly interested in the cloud-street ...
