  1. 1. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Vilma Nordh; [2024]
    Keywords : Numerical modelling; wedge stability; 3DEC; UnWedge;

    Abstract : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.

  5. 4. Development of a CFD model and methodology for the internal flow simulation in a hydrogen-powered UAV

    University essay from KTH/Flygdynamik

    Author : Alessandro Porcarelli; [2021]
    Keywords : Fluid-dynamics; Internal Flow; Scalar Transport; UAV; Fuel Cells; OpenFOAM; Pointwise; Vätskedynamik; internt flöde; skalär transport; UAV; bränsleceller; OpenFOAM; Pointwise;

    Abstract : In the context of an aviation industry whose top priority is to face the sustainability challenge, the growing civil UAV branch is not an exception. Hydrogen-powered UAVs equipped with PEM (Polymer Electrolyte Membrane) fuel cells are more and more frequently identified as the most convincing and promising technology, particularly for long-endurance mission requirements.

  6. 5. Influence from long-distance transport, local sources and precipitation on black carbon concentrations at a rural background field station in southern Sweden

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Kit Ming Yam; [2019]
    Keywords : Black carbon; black carbon concentrations; Hyltemossa station; Aethalometer; HYSPLIT; long-distance transport; local sources; precipitation; Physics and Astronomy; Earth and Environmental Sciences;

    Abstract : The year 2018 was the first complete year with aerosol observations at the rural background station Hyltemossa in southern Sweden. The aim of this thesis was to analyse and investigate the influence from long-distance transport (LDT) aerosols, local sources and precipitation on the black carbon (BC) mass concentration by utilising the Aethalometer and the HYSPLIT model, which estimated the BC mass concentration ([BC]) and simulated the origin of the LDT air masses to Hyltemossa, respectively.
