1. 1. Development of HVAC simulations for truck cabins using OpenFOAM

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Junaid Haider; [2023]
   Keywords : Computational Fluid Dynamics; OpenFOAM; Conjugate Heat Transfer; chtMultiRegionFoam;

   Abstract : In regions with cold climates, a layer of ice often forms on vehicle windshields, whichobstructs the driver’s view. To address this issue, vehicles are equipped with internal defrosters. However, at Scania, the evaluation of defroster design performancecurrently relies on time-consuming and costly physical testing. READ MORE

3. 2. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : William Tönnberg; [2022]
   Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

   Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

4. 3. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

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

   Author : Thibault Desjonquères; [2022]
   Keywords : Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

   Abstract : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. READ MORE

5. 4. Evaluation of pollutant removal performance of stormwater biofilters in a Swedish climate : Comparison of three different filter media designs

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

   Author : Anna Träff; [2022]
   Keywords : Stormwater biofilter; stormwater treatment; cold climate; filter media design; low impact development;

   Abstract : In the recent century, a process of urbanization has increased globally. Previously rural or natural land have been converted into impervious surfaces to make way for housing, industries, and roads. This anthropogenic process has resulted in an increased amount of surface runoff from precipitation, so-called stormwater. READ MORE

6. 5. Carbon Abundance in the Milky Way Galaxy

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Calum Kvernes Macpherson; [2021]
   Keywords : Carbon; Abundance; Milky Way; Chemical Evolution; Physics and Astronomy;

   Abstract : Carbon is the fourth most abundant element after hydrogen, helium and oxygen. It is a product of stellar nucleosynthesis as well as it being an important bio signature for life; this makes the analysis of carbon very fundamental. READ MORE
