1. Grundisolering för flerbostadshus : Jämförelse av cellglas och cellplast avseende energieffektivisering, ekonomiska aspekter och miljöpåverkan
Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : Purpose: This project compares two foundation insulation materials: cellular plastic and cellular glass. Currently, cellular plastic is the most used material for foundation insulation. While cellular glass is not widely utilized. Its disadvantage lies in its higher cost, which makes contractors prefer the cheaper alternative, cellular plastic. LÄS MER
2. Numerical Modelling of a Packed Bed Thermal Energy Storage for Applications in a Carnot Battery : KTH Thesis Report
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This thesis explores the heat transfer characteristics of a packed bed thermal energy storage device through the development of a 3D model in COMSOL Multiphysics. The model is based on a laboratory-scale device consisting of an aluminum box filled with sand, which acts as the thermal storage medium. LÄS MER
3. Numerical study of a jet impacting a heated object
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. LÄS MER
4. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Steel has played an indispensable role in shaping our contemporary world and will persist to play that role for the foreseeable future. However, the steel industry currently is responsible for 7% of the global CO2-emissions, primarily due to the conventional carbon-based reduction process of iron ore. LÄS MER
5. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels
Master-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. LÄS MER
