  3. 2. Explorative Scenarios for Future Lithium Supplies and Demand

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Aksel Rahman; [2023]
    Keywords : lithium mining; lithium future production; Gompertz models; Richards models; Logistic models;

    Abstract : Because of its specific qualities, lithium is a key element for making lithium-ion batteries, which is of great relevance since the battery sector is the fastest growing user of lithium to date and with the transition towards a fully electrified transportation sector due to the current climate agenda and an even bigger increase in demand for lithium is anticipated for the coming decades. The two main sources for lithium to date are mines and brines, with brine water composing around 87 % of the world’s lithium reserves in terms of contained lithium. READ MORE

  4. 3. 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.

  5. 4. Testing macroscopic traffic evacuation models for wildland-urban interface fires

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Adam Ardinge; [2021]
    Keywords : WUI-NITY; WUI; V V; traffic evacuation; WUI fire evacuation; simulation model; verification testing; validation testing; Kincade; Technology and Engineering;

    Abstract : This thesis presents the verification and validation testing performed on the evacuation simulation platform WUI-NITY which has the aim of being a simulation tool for the integration of different layers, such as pedestrian, traffic and wildfire with evolving dynamic interactions. The present thesis aims at applying a set of verification tests and validation testing suitable for WUI-NITY with a focus on the traffic component. READ MORE

  6. 5. Modelling growth of Norway spruce on former agricultural lands in Latvia

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Andis Zvirgzdiņš; [2019]
    Keywords : Norway spruce plantations; young stands; height development; generalized algebraic difference approach; growth simulations;

    Abstract : Adequate growth forecasts are essential for forest management planning. In order to make such forecasts, accurate growth models are required. Due to the rapid growth of Norway spruce (L.) Karst. READ MORE
