  1. 16. Three-way catalyst calibration and system modelling for CNG engine exhaust aftertreatment

    University essay from KTH/Kemiteknik

    Author : Khyati Parikh; [2022]
    Keywords : Three-way catalysts; 1D-Modelling; Kinetic parameters; Calibration; AVL Cruise M; Trevägskatalysatorer; 1D-modellering; Kinetiska parametrar; Kalibrering; AVL Cruise M;

    Abstract : Detta projekt behandlar metodutveckling för att modellera en trevägskatalysator som skulle kunna användas vidare för att uppskatta utsläppen från en Ottomotor. Modellen är byggd i AVL Cruise M för att bestämma omvandlingarna för de tre lagstiftade föroreningarna kolmonoxid, kväveoxider (NOx) och metan baserat på reaktioner som sker i trevägskatalysatorer.

  3. 17. FE Simulation of protective insulation of catalysts in exhaust after-treatment systems of trucks and buses : Investigation and characterization of catalytic converter support mat material for accurate modeling in finite element simulations

    University essay from

    Author : Manroop Bhattasali; [2022]
    Keywords : Catalytic converter; packaging mats; support mats; compression; friction; hyperelastic; hyperfoam; viscoelastic; canning; finite element;

    Abstract : The increase of new and ever more stringent emission legislation has brought about with it a surge in the demand for more sustainable automotive solutions. This has particularly been the case for automobiles, including heavy-duty vehicles like trucks and buses, with internal combustion engines, which now require the design and manufacturing of more durable and reliable components.

  4. 18. Modelling an air handling unit, building and occupant, regarding energy, moisture and frost protection

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Marius Daugela; [2022]
    Keywords : Technology and Engineering;

    Abstract : Frost formation in heat exchangers is an often accruing issue in cold climates. The aim of the project is to calculate the risk of frost formation in different Swedish cities by modeling vapor and frost behavior in heat exchangers... READ MORE

  5. 19. Investigation on how additive manufacturing with post-processing can be used to realize micronozzles

    University essay from Uppsala universitet/Ångström Space Technology Centre (ÅSTC)

    Author : Alan Bugurcu; [2022]
    Keywords : additive manufacturing; micronozzle; micro rocket nozzle; laser-powered powder bed fusion; electropolishing; supersonic micronozzle; supersonic micro rocket nozzle; titanium alloy; titanium-64; Ti-Al6-V4;

    Abstract : This is predominantly a qualitative study on the manufacturing of micronozzles with an additive manufacturing (AM) technique, namely the laser-powered powder bed fusion (PBF-LB).  Manufacturing of micronozzles with standard microelectromechanical system technology often results in 2.

  6. 20. Accuracy verification of GT-Power model and reduction of computational time

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Viktor Dahl; Maja Dyrsmeds; [2022]
    Keywords : Vehicle acoustics; GT-Power; Exhaust system; Internal combustion engine;

    Abstract : The noise produced by any new vehicles is tightly regulated by the European Union which have developed a standardised method for measuring the emitted noise of new vehicles. The method involves a vehicle driving past carefully positioned microphones at a specific range of engine speeds. READ MORE
