1. 1. Inverse Atmospheric Dispersion Modeling in Complex Geometries

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Charlie Pelland; [2022]
   Nyckelord :atmospheric dispersion modeling; dispersion modeling; invers dispersion modeling; atmospheric dispersion; invers atmospheric dispersion; CFD; computational fluid dynamics; radioactive release; openfoam; CRBN; dry deposition; dry deposition velocity; scavenging effect; wet deposition; optimization model; Reynolds Averaged Navier-Stokes; adjoint mode; time-dependent rain simulation; time-dependent rain; time dependent rain simulation; time dependent rain;

   Sammanfattning : In the event of a radioactive release in an urban environment the consequent response mustbe swift and precise. As soon as first responders have correct information, they can make anaccurate risk assessment. However, if the position, release rate and time of the radioactiverelease is unknown it is hard to know how the pollutant will spread. LÄS MER

3. 2. Mass conservative network model for convective net flow in a complex urban geometry

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Linus Olofsson; [2016]
   Nyckelord :Network model; Street canyons; Intersections; Urban dispersion; CFD data; CFD simulations; Atmospheric exchange;

   Sammanfattning : When simulating air flows in an urban environment, for e.g. pollutant dispersion investigations, today's main tool is advanced computational fluid dynamics simulations. These simulations take a lot of time and resources to perform, even for small geometries. LÄS MER
