1. 1. Evaluation of a stochastic model of coherent turbulent structures for atmospheric particle deposition applications

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Andreas Eriksson; [2022]
   Keywords : atmospheric dispersion; particle deposition; k-epsilon; RANS; lagrangian particle model; stochastic particle model; OpenFOAM; SIMPLE algorithm; ABL; atmospheric boundary layer; neutral boundary layer; coherent turbulent structures;

   Abstract : In this thesis, we have evaluated a stochastic Lagrangian model for computing particle deposition rates with prospects to use for atmospheric deposition applications.  The model is one-dimensional and models the particle dynamics in the boundary layers near walls and obstacles by simulating the coherent turbulent structures and Brownian motion governing the wall-normal transport.

3. 2. Transport of non-spherical particles in pipeflow with suction

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Emil Wångby; [2020]
   Keywords : Brownian motion; Non-spherical particles; Pipe flow;

   Abstract : The interest of how small non-spherical particles transport behaviour when transported in pipe-flow is of large interest in a variety applications. This kind of theory have been used when studying composite manufacturing and how particles behaves in the human lungs. READ MORE
