  1. 36. Studie av verkningsgrad potentialen för ett vatten baserat Waste Heat Recovery system med kolvexpander

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :HOUSSAM ACHKOUDIR; Naowar Hanna; [2011]
    Nyckelord :;

    Sammanfattning : SammanfattningEn ånganna monterades i EGR (Exhaust Gas Recirculation) slingan på en 12,7 liters Scania Euro V motor (DC1306). En modell som beskriver Rankine cykel togs fram med vatten som köldmedium i simuleringsverktyget GT-Power. Ångpannan i GT-power modellen kalibrerades m.h. LÄS MER

  3. 37. Assessment of humidity management effects on PEM fuel cell performance

    Master-uppsats, KTH/Energiteknik

    Författare :Ose Micah Osamudiamen Ose Micah; [2011]
    Nyckelord :PEM Fuel Cell.;

    Sammanfattning : The electrical energy output and the performance of a PEM fuel cell is dependent on the ion transfer in the fuel cell. The ion transport mechanism in the electrolyte cell membrane is dependent on the charge site in the membrane. LÄS MER

  4. 38. Simulation of a lab-scale methanation reactor

    Master-uppsats, KTH/Kemiteknik

    Författare :Seyedeh Guilnaz Mirmoshtaghi; [2011]
    Nyckelord :Biogas; methanation reactor; Ruthenium catalyst; isothermal; adiabatic;

    Sammanfattning : By the everyday increasing enthusiasm for using renewable-sustainable sources in energy production area, focusing on one and optimizing it in the best possible way should be of much interest. Biogas production from anaerobic digestion of wastes is a well known energy source which could be applied more efficiently if the CO2portion of it would be upgraded to CH4as well. LÄS MER

  5. 39. Transportation of separate waste fractions in an underground waste transportation system

    Master-uppsats, KTH/Industriell ekologi

    Författare :Satomi Shibutani; [2010]
    Nyckelord :waste transporting; underground pipe system; waste fraction cross contamination; optimum transporting conditions;

    Sammanfattning : Today waste management has entered a new stage. Since wastes still contain natural materials and energy that can be extracted, it should be treated in effective ways, for example, for energy recovery or material recycling. LÄS MER

  7. 40. Radialtätning till Retarder

    Master-uppsats, Fluid och mekanisk systemteknik

    Författare :Olov Danielsson; Johan Karlsson; [2009]
    Nyckelord :Retarder; Radialtätning; Tätning;

    Sammanfattning : This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. LÄS MER
