1. 1. Analysis of free-riding behaviour using instrumented bicycles

   University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

   Author : Jonathan Johansson; [2023]
   Keywords : Data collection; instrumented bicycle; free-riding; conventional bicycle; electric bicycle; naturalistic data;

   Abstract : The use of bicycle as a transportation mode has increased in popularity during the last four decades. The reasons that could explain why the use of bicycles have increased in popularity are many. READ MORE

3. 2. Simulation of air quality in underground train stations

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Benjamin Söderberg; [2020]
   Keywords : PM10; aerosols; air pollution; particulate matter; emission factors; underground train station; PM10; luftkvalité; tåg; emissionsfaktorer; underjordiska tågstationer;

   Abstract : Particulate matter (PM) is a widespread air pollutant of microscopic particles that are suspended in the atmosphere. There is high concentration of PM in underground train stations and tunnels. The concentration of particulate matter (PM10) measured in Stockholm’s metro varies significantly between day and nighttime traffic of trains. READ MORE

4. 3. Simulation of Colorless Distributed Combustion

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Hampus Olsson; [2019]
   Keywords : Computational Fluid Dynamics; Combustion; Gas Turbine; Emission reduction; Flameless Combustion; Colorless Distributed Combustion; Technology and Engineering;

   Abstract : Colorless distributed combustion (CDC) is a promising novel technology to reduce emissions of carbon monoxide and nitrogen oxides in gas turbine combustors. CDC features a different flame regime than conventional gas turbine combustors, associated with a distributed reaction zone and low and uniform temperatures due to dilution of combustion air with exhaust gases.

5. 4. Flow and Air Quality Modelling of a Car Cabin

   University essay from Umeå universitet/Institutionen för fysik

   Author : Oskar Jolérus; [2019]
   Keywords : CFD; PM2.5; Air quality; Multiphase; LPT;

   Abstract : Adverse health effects attributable to both short- and long-term exposure to air pollution have turned the focus on different microenvironments. The interior of vehicles is of relevance as road traffic emissions and re-suspension of road dust are major sources of pollutants associated with adverse health effects. READ MORE

6. 5. Investigation of reaction properties to facilitate chemical lumping of kinetic mechanisms

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

   Author : Frej Ryde; [2019]
   Keywords : Combustion; Simulation; Chemical lumping; Mechanism reduction; Ant colony reduction; Hybrid optimization; Physics and Astronomy;

   Abstract : Combustion process are used to improve modern society, but it comes with problems, like global warming and air pollution. Computer simulations are used to study combustion process to allow more efficient use of the fuel or decrease the creation of pollution. READ MORE
