  1. 1. Modeling Diesel spray combustion using a Detailed Chemistry Approach

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Jonas Edman; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The rapid development of computer hardware during the past decade has contributed substantially to advances in almost all branches of science. Computer modeling is being applied to increasingly small physical scales and increasingly large domains, facilitating the generation of advanced phenomenological models and models based on first principles.

  2. 2. On tribological design in gear tooth contacts

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ellen Bergseth; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction; gear contact; gear manufacturing; surface boundary layers; surface topography; wear;

    Sammanfattning : The correct tribological design will have a considerable effect on a gear’s service life and efficiency. The purpose of this thesis is to clarify the impact of variation in the gear tooth flank tribological system on the gear contact load capacity – to increase the understanding of how surface topography and lubricant interact.

  3. 3. On the Load Distribution and Design of a Chain Drive

    Detta är en avhandling från Machine Elements Division, P.O.Box 118,SE- 22100 Lund,Sweden

    Författare :Ingvar Troedsson; Lund University.; Lunds universitet.; [1999]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tension force; tensioner; oscillation; chain drive; vibration; load distribution; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. LÄS MER

  4. 4. Demand Side Activities for Electric Load Reduction

    Detta är en avhandling från Department of Energy Sciences, Lund University

    Författare :Juozas Abaravicius; Lund University.; Lunds universitet.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Load demand; Energiforskning; Energy research; demand response; peak load reduction; load management; demand side;

    Sammanfattning : The research described in this thesis, focuses on some activities on the demand side that could reduce peak load in electricity system by using consumer flexibility i.e. by increasing the demand side response to signals coming from the energy market. LÄS MER

  5. 5. Mechanical Analysis of Lubrication and Lubricants

    Detta är en avhandling från Division of Machine Elements, Department of Mechanical Engineering, Lund Institute of Technology

    Författare :Jonas Ståhl; Lund University.; Lunds universitet.; [2002]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; Maskinteknik; hydraulik; akustik; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering;

    Sammanfattning : This thesis comprises three different topics within the field of tribology. First, design functions for analyses of slider bearings are developed. Second, a lubricant model applied to elastohydrodynamically lubricated (EHL) line contacts considering wall-slip is presented. LÄS MER
