1. 1. 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

3. 2. Comparison of a hybrid ventilation system and a mechanical ventilation system with heat recovery through life cycle assessment : A case study of a modern Danish office building

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Josefine Nilsson Willkomm; [2020]
   Keywords : life cycle assessment; ventilation system; environmental impact; hybrid ventilation system; mechanical ventilation system with heat recovery; livscykelanalys; ventilationssystem; miljöpåverkan; ventilation; hybrid ventilationssystem; mekaniskt ventilationssystem med värmeåtervinning;

   Abstract : The building sector is responsible for 36% of the energy usage and 39 % of all CO2- emissions in European union (EU). Therefore, it is of great interest to investigate how the building sector can become more energy efficient and lower the environmental impact. READ MORE

4. 3. A hybrid low - temperature heating system in geothermal retrofitting for public buildings in the Mediterranean climate

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Boumediene Bizimana; [2019]
   Keywords : Hybrid low-temperature floor heating; Energy performance; Thermal comfort; Indoor air quality; Lågtemperaturgolvvärme; Energiprestanda; Termisk komfort; Inomhusluftkvalitet;

   Abstract : More than 50 % of EU’s yearly energy demand is spent on heating and cooling systems with which most of its source is generated from non-renewable fossil fuel [1]. Furthermore, half of the EU buildings are heated with a non-efficient boiler of about 60% or less efficiency [1]. READ MORE

6. 5. Engineered wood glass combination : Innovative glazing façade system

   University essay from KTH/Byggnadsmaterial

   Author : Alessandra Tapparo; [2017]
   Keywords : wood; glass; combination; engineered products; EWGC; façade; panel; sustainability;

   Abstract : Buildings require a lot of energy during all their lifetime, from the construction site to the use and demolition. The building sector contributes to a large part of the total emissions of greenhouse gases and consume a large amount of water and energy resources, so the material components used in the building sector have gained an important role in the discourse of sustainability.
