1. 1. Insights Into Wind Profile Characteristics in the Arctic Marine Boundary Layer

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

   Author : Charlotte Sophie Gausa; [2024]
   Keywords : Arctic; wind profile power law; MOST; boundary layer; low level jets; sea ice; vindprofil; Arktis; gränsskikt; vindenergi; låghöjdsvindar; havsis;

   Abstract : The atmospheric boundary layer in the Arctic is essential for the understanding of climate change and improving regional weather prediction. The aim of this study is to investigate to which degree wind speed profiles retrieved in the Arctic agree with well known wind profile concepts and understand which local impact factors influence the wind speed profile.

3. 2. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

   University essay from KTH/Energiteknik

   Author : Lorenzo Centonze; [2023]
   Keywords : ;

   Abstract : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.

4. 3. PGE Geochemistry and Mineralogy of Dunite, Chromitite, and Laterite Samples from the Acoje Ophiolite Block, Philippines

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Michelle Dossey; [2023]
   Keywords : PGM; PGE; laterite; limonite; chromitite; dunite; platinum group minerals; platinum group elements; Acoje; Philippines;

   Abstract : Ni-laterites have the potential to become unconventional ore deposits for platinum group elements (PGE). This study was conducted to determine enrichment trends of PGE as a result of the Ni-laterization process. READ MORE

5. 4. On intermittency in the turbulent asymptotic suction boundary layer

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Edoardo Foschi; [2023]
   Keywords : Turbulence; turbulent boundary layer; intermittency; numerical simulation; DNS; tripping; suction;

   Abstract : This thesis presents a series of direct numerical simulations (DNS) performed in order to understand the discrepancy in the literature regarding turbulent asymptotic suction boundary layers (TASBLs) at low Reynolds numbers. The hypothesis to be tested is that the main reason for higher turbulence intensities observed in experiments compared to DNS is that the latter exhibits intermittent patches of laminar flow, developing both temporally and spatially.

6. 5. Methods and Purposes of Aerodynamic Correlation in Formula Student

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Alix Le Bastard; [2023]
   Keywords : Technology and Engineering;

   Abstract : This thesis investigates how methods of aerodynamic validation can assist a formula student team in designing their aerodynamic package. When de- signing their aerodynamic components, formula student team mostly rely on CFD software simulations, but there is no guarantee that the simulations de- pict properly the physical behaviour of the airflow around the car.
