  2. 16. Investigating Effects of Water Injection on SI Engines

    Author : Jayesh Khatri; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knock Mitigation; Downsized SI engine; RON; Water Injection; Particulates; Relative Humidity;

    Abstract : In recent years, there has been a major shift towards the partial or complete electrification of vehicles that have traditionally been powered by conventional internal combustion (IC) engines; almost all major automotive manufacturers have rightly stated that they will make such a shift. This has been motivated in large part by pressure from governments and policymakers to minimize vehicular emissions, especially those of the greenhouse gas CO2, in order to control climate change.

  4. 17. Computational Studies on Homogeneous Water Oxidation Catalysts

    Author : Ge Li; Mårten S. G. Ahlquist; Moyses Araujo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational studies; homogeneous; water oxidation catalysts; ruthenium; iron; mechanisms; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. READ MORE

  5. 18. Diffusion of Water in Foods during Heating

    Author : Karin Thorvaldsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; mass transfer; mass transport; porous; water; moisture; heat; food;

    Abstract : The overall aim of this research was to improve the knowledge of diffusion of water in foods during heating, so that the final quality of foods after heat processing could be predicted and controlled. The work consisted of three main parts. The first part involved the development of a method to study the diffusion. READ MORE

  6. 19. A numerical investigation of energy conversions in geophysical boundary layers

    Author : Patrik Andreasson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : The detailed energy conversions in turbulent geophysical boundary layers are examined and quantified. The governing transport equations are solved by utilizing turbulence modelling. Different turbulence closures have been adopted for the boundary layers examined. READ MORE

  7. 20. Electrochemical water splitting based on metal oxide composite nanostructures

    Author : Aneela Tahira; Omer Nur; Magnus Willander; Rasit Turan; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Composite metal oxides; hydrothermal method; water splitting; Tafel slope; stability; durability; alkaline media; acidic media;

    Abstract : The occurrence of available energy reservoirs is decreasing steeply, therefore we are looking for an alternative and sustainable renewable energy resources. Among them, hydrogen is considered as green fuel with a high density of energy. READ MORE
