  1. 1. Acoustic Characterization of Catalyst

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Surachit Dokson; [2023]
    Nyckelord :;

    Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER

  3. 2. IC-Engine Source Characterisation and exhaust system simulations

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Pontus Gräsberg; [2021]
    Nyckelord :IC-engine; source characteristics; Multiload method; one-port source; exhaust system; Bränslemotor; källkarakterisering; avgassystem;

    Sammanfattning : To be able to predict the sound pressure level emitted by a exhaust system one must be able to describe the source. The source in the form of an engine can linearly be described as a source strength and a source impedance. An IC-engine can acoustically have a non-linear part meaning that the source characteristics have a dependency on the load. LÄS MER

  4. 3. Evaluation of decentralized ventilation system with heat recovery

    M1-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Sunkavalli Kowshik Chowdary; [2020]
    Nyckelord :Decentralized ventilation; airflow; air draught; heat exchangers; tracer gas; Technology and Engineering;

    Sammanfattning : Humans spend 90% of their times indoors, and maintaining a pleasant indoor environment is essential. Factors like human behaviour, combustion sources, cleaning supplies, affect the indoor environment, which could potentially affect the human health.the most common answer to controlling the indoor environment is a good HVAC system.

  5. 4. Experimental Study to Reduce CO Emissions in Skellefteå Kraft's 16 MW Bubbling Fluidized Bed Boiler

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :William Johansson; [2019]
    Nyckelord :;

    Sammanfattning : Skellefteå Kraft has had high CO emissions problems in a bubbling fluidized bed (BFB) boiler in Malå.Statistical emissions data from 2013 to 2019 shows plant average emissions of 1230 ppm. Thisexceeds the recommended 440 ppm (6 % O2) that Naturvårdsverket proposes (Naturvårdsverket,2005). LÄS MER

  7. 5. Pressure and Temperature Measurements in a Heavy-Duty Diesel Engine

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Paul Linschoten; [2018]
    Nyckelord :;

    Sammanfattning : The values measured by the temperature and pressure sensors in the gas exchange system are important input parameters for several engine systems. This report focuses on the measurement and signal analysis of pressure and temperature, obtained at different positions within the intake and exhaust manifolds of a heavy-duty Scania diesel engine.
