  1. 16. Policy Tools for the Decarbonisation of Urban Freight Transport in Brazil

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Raghav Somayya Mandana; [2021]
    Keywords : CO2 emissions; transport sector; decarbonisation; battery electric vehicles BEVs ; electromobility; freight transport; total cost of ownership TCO ; light commercial vehicles LCVs ; Koldioxidutsläppen; transportsektorn; avkolning; elektriska fordon EF ; elektromobilitet; godstransport; total ägandekostnad TÄK ; lätta kommersiella fordon LKF ;

    Abstract : There has been an increase in the carbon dioxide (CO2) emissions in the last 3 decades. A large share of these emissions is produced by the transport sector. In 2010 alone, global transport accounted for 7 GtCO2 eq and approximately 23% of total energy-related CO2 emissions. READ MORE

  4. 18. Shape optimization of axial cooling fan via 3D CFD simulation and surrogate modeling

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Martin Granlöf; [2021]
    Keywords : Fan noise; shape optimization; mesh morphing; computational fluid dynamics; computational aeroacoustics; Efficient Global Optimization; Reynolds-averaged Navier-Stokes;

    Abstract : Due to legislative reasons and environmental concerns the automotive and transport sector are shifting their focus from traditional internal combustion engine (ICE) vehicles to development of battery electric vehicles (BEVs). This brings new challanges to design of cooling systems where axial fans are one of the key components. READ MORE

  5. 19. Infrastructure for Electromobility-available options, Sustainability and the Future

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Chukwuemezie Okeke; [2021]
    Keywords : ;

    Abstract : Electric Vehicles (EVs) are regarded as promising vehicles for the future, and has been greatly focused on by automotive manufacturers across the world to solve the massive greenhouse gas emission from the transportation sector. Unfortunately, because of the challenges of limited batteries capacity, high purchase cost, lack of charging infrastructure and lack of supporting government policies in developing countries, the technology uptake has been limited.

  6. 20. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Zapata Tamayo Juan Guillermo; [2021]
    Keywords : micropitting; mild sliding wear; surface coating; diamond-like carbon DLC; glycerol-based lubrication; green lubricant; rolling contact fatigue; rolling-sliding;

    Abstract : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.
