User's guide for numerical modeling of buoyant plumes in a turbulent, stratified atmosphere
Abstract
A widely applicable computational model of buoyant, bentover plumes in realistic atmospheres is constructed. To do this, the twodimensional, timedependent fluid mechanics equations are numerically integrated, while a number of important physical approximations serve to keep the approach at a tractable level. A threedimensional picture of a steady state plume is constructed from a sequence of timedependent, twodimensional plume cross sectionseach cross section of the sequence is spaced progressively further downwind as it is advected for a progressively longer time by the prevailing wind. The dynamics of the plume simulations are quite general. The buoyancy sources in the plume include the sensible heat in the plume, the latent heat absorbed or released in plume moisture processes, and the heating of the plume by a radioactive pollutant in the plume. The atmospheric state in the simulations is also quite general. Atmospheric variables are allowed to be functions of height, and the ambient atmospheric turbulence (also a function of height) is included in the simulations.

A set of equations describing the behavior of atmospheric plumes is derived in which special attention is given to the modeling of the microphysical processes and the treatment of the turbulence. An original numerical scheme for solving these equations is studied, and a FORTRAN IV computer code is discussed. Simulations using real atmospheric data are compared with onsite plume measurements. The model is found to accurately predict the flow characteristics of the plumes and the dispersal of water vapor in the most complex atmospheres.

Behaviour of buoyant moist plumes in turbulent atmospheres. Final report
A widely applicable computational model of buoyant moist plumes in turbulent atmospheres has been constructed. To achieve this a one dimensional Planetary Boundary Layer (P.B.L.) model has been developed to account for atmospheric turbulence while the two dimensional time dependent fluid mechanics equations which govern plume behavior are numerically integrated. A cloud microphysics model has been incorporated into the basic numerical code to account properly for the water content of the plume. The overall dynamics of the plume is quite general. The buoyancy source in the plume includes both the sensible heat and the latent heat absorbed or released inmore » 
Numerical electromagnetics code  method of moments. User's guide supplement for NEC3 for modeling buried wires
NEC3 is a version of the Numerical Electromagnetics Code  Method of Moments that has been extended to model wires that are buried or penetrate the groundair interface. Fields in the presence of an interface are obtained by interpolation or leastsquares approximation using tables generated by an auxiliary program SOMNTX which evaluates Sommerfeld integrals. Asymptotic approximations for the field are used at larger distances. This approach is similar to that used in NEC2 for wires above the interface, but now includes reflected field below the interface and field transmitted across the interface. NEC3 retains all of the capabilities of NEC2,more » 
HGSYSTEM/UF{sub 6} model enhancements for plume rise and dispersion around buildings, liftoff of buoyant plumes, and robustness of numerical solver
The HGSYSTEM/UF{sub 6} model was developed for use in preparing Safety Analysis Reports (SARs) by estimating the consequences of possible accidental releases of UF{sub 6} to the atmosphere at the gaseous diffusion plants (GDPs) located in Portsmouth, Ohio, and Paducah, Kentucky. Although the latter report carries a 1996 date, the work that is described was completed in late 1994. When that report was written, the primary release scenarios of interest were thought to be gas pipeline and liquid tank ruptures over open terrain away from the influence of buildings. However, upon further analysis of possible release scenarios, the developers ofmore »
