Predictions of the Flow in the Intake Port of an Engine Using LES and PANS
The airflow in the cylinder of a car engine is simulated using three different techniques. Large Eddy Simulations (LES), Partially Averaged Navier-Stokes (PANS) and Reynolds Averaged Navier-Stokes (RANS). The simulations are compared with experimental data from BMW and a benchmark designed by BMW, …

Landbaserad rening av barlastvatten, ett realistiskt alternativ för Göteborgs hamn? – Nuvarande situation och framtida förutsättningar
Problemet med “invasiva arter” som sprids med fartygs barlastvatten och påverkar marina ekosystem är så stort att FN-organet International Maritime Organization (IMO) år 2004 beslutade att anta en konvention med syfte att bekämpa ytterligare spridning. Då konventionen trätt i kraft kommer …

Kontorshotell Jonsereds fabriker - Fastighetsutveckling av gammal verkstadslokal
This report presents suggestions and recommendations on how to convert an old industrial building, built in 1958, to an office hotel. One of the main criteria was that the floor plan should be flexible. The building is situated at Jonsereds Fabriker and the study was conducted for Hantverkslokaler …

Hållbar renovering av befintlig bebyggelse, En jämförelse av tre energieffektiva byggmetoder
Efterfrågan på mer miljövänliga och energieffektiva byggnader har ökat de senaste åren och en bidragande orsak till detta är det ständigt ökande energipriset. Idag står bebyggelsen i Sverige för ungefär 40 % av den totala energianvändningen och debatten om energieffektivt boende är högst aktuell då …

The Effect of Advanced Automatic Collision Notification (AACN) on Road Fatality Reduction in Sweden
Road traffic accidents account for approximately 1.3 million fatalities each year and are the eighth most common cause of death globally and the leading cause of death for people between the age of 15 and 29. The outcome of a collision is affected by actions taken before, during, and after the …

Distribution of bed material in a Horizontal Circulating Fluidised Bed boiler
A conventional circulating fluidised bed (CFB) boiler has a limitation due to the height of the furnace, when implemented in smaller industrial facilities. The design of a horizontal circulating fluidised bed (HCFB) boiler is an interesting approach to resolve this problem. Enabling the benefits, …

Simulation Study on Lifted Hydrogen and Methane Jet Flames in Hot Vitiated Coflow
Combustion of fossil fuels is the most important energy source today. Burning fossil fuel is however expensive and bad for the enviroment. Improving the combustion technology to reduce fuel consumption, and to be able to burn renewable fuels is therefore of great importance. Analysing the flames in …

Integrated life cycle design : application to concrete multi-dwelling buildings
This work examines the application of ILCD (Integrated Life Cycle Design), to Swedish concrete multi-dwelling buildings. The aim of the study is to look into methodological issues of ILCD and to present the fundamental attributes of dwelling buildings and how they relate to concrete as a structural …
