3D plume modeling of SPT-100
… a well known, stationary plasma thruster SPT-100 plume modeling was performed using a hybrid MPI-GPU AMR code CHAOS. Xe atoms, Xe+, and Xe+2 ions are modeled using a kinetic approach. Modeling electrons using a kinetic approach is not feasible in today's computational power for a Hall thruster …

Power plant carbon dioxide emission quantification with plume modeling
… originating from point sources, referred to as plumes, can be simulated using mathematical and physical models, such as a convection-diffusion plume model and a Gaussian plume model. The convection-diffusion model is based on the convection-diffusion partial differential equation describing mass …

Modeling carbon dioxide particle releases in the deep ocean
… via the solute density effect. Hence, the total plume thickness of a negatively buoyant CO₂ hydrate plume may exceed that of positively buoyant CO₂ release. This is seen as a potential advantage both in terms of dilution and sequestration depth. A brief description of the two-phase integral plume …

Evaluation of displacement ventilation for use in high-ceiling facilities
… to have significant impact by generating large plume flows and contributing substantially to the total radiative incident loading to the floor. Experimental results could not justify the use of a constant temperature gradient assumption to estimate the temperature difference between head and …

Interagency Modeling Atmospheric Assessment Center local jurisdiction: IMAAC operations framework
The Interagency Modeling Atmospheric Assessment Center (IMAAC) is a Department of Homeland Security (DHS) interagency working group responsible to create atmospheric air plume dispersion model predictions for designated emergencies. When 'activated' IMAAC is comprised of representatives from eight …

Modeling Differential Charging of Composite Spacecraft Bodies Using the Coliseum Framework
… is a tool designed for electric propulsion plume interactions. Virginia Tech has been developing a module for COLISEUM called DRACO, a particle-in-cell based code capable of plume modeling for geometrically complex spacecraft. This work integrates a charging module into DRACO. Charge is …

Water Quality Study and Plume Behavior Modeling for Lake Pontchartrain at the Mouth of the Tchefuncte River
… water quality in the area and to simulate the plume patterns from the Tchefuncte River. Twenty eight stations at the mouth of the Tchefuncte River, and a station at the Madisonville Bridge were selected for study on the basis of proximity to the mouth of the River. Fecal coliform counts were …

Plume Dispersion Modeling of Chlorine Gas Released Due to Ballistic Attack on Chlorine-Carrying Railway Tanker
… were verified against actual experiments and plume theories and were used to model the chlorine gas plumes resulting from such an attack. Locations of interest were Chicago, IL due to its urbanized area and skyscrapers and Jackson, MS because of its relatively flat terrain and wooded areas. …
