  1. 1. Computational Analysis of Spray Deflector Designs

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Osman Gyokhan Ali; [2023]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Thermal Comfort, CO2 and Humidity Levels in Library Student Rooms at the University of Gävle : Experimental and Numerical Study

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Ibai Elosua Ansa; [2022]
    Nyckelord :Ventilation rate; air renewal; CO2 level; relative humidity; indoor temperature; sensors;

    Sammanfattning : Human performance and health are one of the most relevant topics in modern society. Especially at young ages, when academic performance is indispensable. Thus, as the human being spends most of its lifetime inside a building, thermal comfort has become an essential aspect of a room. LÄS MER

  4. 3. Improving thermal comfort while managing the constraints of the prison environment : Study of the construction project of the Marseille prison "Les Baumettes 3" and proposal of a thermal comfort strategy in the design phase

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Cassandre Druere; [2022]
    Nyckelord :;

    Sammanfattning : In France, a prison construction plan has been launched under the presidency of Emmanuel Macron to improve the living conditions of prisoners. The aim of this plan is of course to provide decent living conditions for prisoners but also to promote their reintegration. LÄS MER

  5. 4. CFD study of the different inlet configurations and airflows in a room with IJV

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Christos Stiapis; [2022]
    Nyckelord :Ventilation; CFD; Impinging Jet Ventilation;

    Sammanfattning : A method of providing ventilation using impinging jets (IJV) utilizes stratification while delivering air at a high velocity. As a result of this attribute and the simplicity of its terminal construction, IJV offers an advantage over the well-known Displacement Ventilation (DV) system. LÄS MER

  7. 5. Numerical Investigation of the Near FieldZone Flow Behavior of Isothermal CornerImpinging Jet Ventilation Using CFD

    Master-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :Too-chukwu C. Ogbuagu; [2021]
    Nyckelord :Ventilation; Computational fluid dynamics;

    Sammanfattning : Abstract The impinging jet ventilation's importance in providing better air distribution and energy-efficient operation, as well as both its heating and cooling flexibility potential cannot be overemphasized. This is because acceptable indoor air quality and its environmental conditions are essential to occupant’s wellbeing, comfort, productivity, and improved cognitive function. LÄS MER
