Partikkelveier

Partikkelveier is a Norwegian term that translates to particle paths or paths of particles. The concept is used in several technical and scholarly contexts to describe the routes that individual particles take through a system, either physically or in computational models. The term is often employed in discussions of transport, dispersion, and tracer studies.

In physics and engineering, partikkelveier refer to the trajectories of particles moving in flows, such as droplets in microfluidic channels, aerosol particles in air, or solute particles in porous media. These trajectories are typically analyzed within a Lagrangian framework, where the position of each particle is tracked over time, in contrast to Eulerian descriptions that focus on fields at fixed locations.

In computer simulation and data analysis, partikkelveier describe the computed paths of particles in discrete-particle methods, such as particle-tracking techniques, smoothed-particle hydrodynamics, or agent-based transport models. They are obtained by integrating the governing equations of motion using surrounding velocity, force, and interaction fields.

In environmental science and urban planning, the term may be used more informally to discuss how particulate matter travels through air or water, with implications for exposure assessment, mitigation strategies, and policy design.
