  1. 1. High-speed optical and laser diagnostics - Internal combustion engines and gas turbine applications

    Författare :Saeed Derafshzan; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysicumarkivet A:2023:Derafshzan;

    Sammanfattning : Increasing demands to meet regulations on combustion emissions and their environmental impact, and the need to improve their efficiency in different applications, have been the centre of focus in research and industry for decades. Optical and laser diagnostics have been proven to be amongst the best available tools due to their remote nature and non-intrusiveness, high spatial and temporal resolution, and their ability to investigate combustion processes and emissions in ways unprecedented before.

  3. 2. An Interactive Traction Motors Design and Selection Software

    Författare :Hasan El Hinaoui-Hamze; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAD; Access; Electric Drives; Visual Basic; Internal Combustion Engines ICEs ; · Electric Motors EMs ; SQL; MATLAB; Hybrid Electric Vehicles HEVs ; Traction Motors; MagNet;

    Sammanfattning : Use of electric motors in vehicle traction, in fact, predates the internal combustion engines (ICEs). Electric vehicles powered by dc motors were known as far back as 1890. Compared with vehicles powered by ICEs, the main drawback of the early electric vehicles was, and still is, their limited range and long recharging time. LÄS MER

  4. 3. Precision cooling for C02 reduction

    Författare :Sudharsan Vasudevan; Chalmers tekniska högskola; []

    Sammanfattning : Global climate is adversely affected by increasing emissions of carbon dioxide and other green-house gases. The road transport sector contributes significantly to these emissions. LÄS MER

  5. 4. Centrifugal compressor flow instabilities at low mass flow rate

    Författare :Elias Sundström; Mihai Mihaescu; Håkan Nilsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Centrifugal Compressor; Large Eddy Simulation; Internal Com- bustion Engine; Aeroacoustics; Modal Flow Decomposition;

    Sammanfattning : Turbochargers play an important role in increasing the energetic efficiency andreducing emissions of modern power-train systems based on downsized recipro-cating internal combustion engines (ICE). The centrifugal compressor in tur-bochargers is limited at off-design operating conditions by the inception of flowinstabilities causing rotating stall and surge. LÄS MER

  7. 5. Application and Development of Optical Soot Diagnostic Techniques

    Författare :Ted Lind; Förbränningsmotorer; []
    Nyckelord :Soot; Soot diagnostics; Soot oxidation; Extinction Imaging; Soot thermometry; Optical diagnostics;

    Sammanfattning : Internal combustion engines (ICE) have been a vital part of society ever since their inception more than a hundred years ago. While initially it seemed as if the replacement of horse and carriage had solved the issue with pollutant emissions, it became evident in the 60’s that emission from ICEs is a major concern. LÄS MER
