  1. 1. Forming wide-orbit planets via pebble accretion

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

    Author : Nerea Gurrutxaga; [2023]
    Keywords : Planet Formation; Pebble Accretion; Protoplanetary Disk; Wide-Orbit Planet; Physics and Astronomy;

    Abstract : The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. READ MORE

  3. 2. CFD Analysis of Engine Room Temperature : CFD Analysis of Engine Room Temperature: Case study The Grange Castle Power Plant Project

    University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Author : William Wanli; [2023]
    Keywords : CFD Computational Fluid Dynamics; ventilation system; temperature; airflow; engine room.;

    Abstract : Computational Fluid Dynamics (CFD) has emerged as an indispensable tool in various engineering fields, particularly in the design and optimization of HVAC systems in complex environments, such as engine rooms. This paper presents a comprehensive overview of CFD applications and focuses on the engine rooms of the Grange Castle Power Plant in Dublin, Ireland. READ MORE

  4. 3. Computational Analysis of Spray Deflector Designs

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Osman Gyokhan Ali; [2023]
    Keywords : Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

    Abstract : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. READ MORE

  5. 4. Uncertainty quantification for offshore wind turbines

    University essay from KTH/Matematik (Avd.)

    Author : Ziming Wang; [2022]
    Keywords : wind energy; uncertainty propagation; polynomial chaos; Rosenblatt transformation; quadrature; regression; vindenergi; osäkerhetsutbredning; polynomkaos; Rosenblatt transformation; kvadratur; regression;

    Abstract : Wind energy is a field with a large number of uncertainties. The random nature of the weather conditions, including wind speed, wind direction, and turbulence intensity, influences the energy output and the structural safety of a wind farm, making its performance fluctuate and difficult to predict.

  6. 5. Study of luminescent and energy properties of CsPbBr3 and CsPbI3 nanoplatelets

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Taddeo Salique; [2022]
    Keywords : quantum confinement; nanoplatelets; CsPbBr3; CsPbI3; semiconductor; exciton; perovskite nanocrystals;

    Abstract : Halide perovskite semiconductor nanocrystals have been studied a lot recently because they allow a precise control over the entire visible emission spectrum and as a result, the possibility of a variety of light-emitting applications. In this study, cesium lead bromide CsPbBr3 and cesium lead iodide CsPbI3 nanoplatelets of 3, 4 and 5 monolayers (ML) have been synthesized. READ MORE
