  1. 1. Optimization of Thermal Comfort on Electric Buses : A Comprehensive Study on Passenger Satisfaction in Stockholm, Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ellinor Hambraeus; Maxwell Minotta Cuervo; [2023]
    Nyckelord :Electric bus; Bus temperature; Thermal comfort; Energy efficiency; Predicted Mean Vote; Equivalent temperature v; Elbuss; busstemperatur; termisk komfort; energieffektivisering; Predicted Mean Vote; Ekvivalent temperatur vii;

    Sammanfattning : The transition towards electrification in the bus sector is necessary to achieve the global climate goals and has gained significant traction in recent years. However, there are critical challenges associated with this transition, one of them being the absence of excess heat that traditional combustion engines provided to warm the bus cabin. LÄS MER

    Sammanfattning : I detta examensarbete simuleras ett värmehanteringssystem i Matlab Simulink för en elektrisk lastbil, det för att värmehantera fordonets klimat. Där en värmepump används för nedkylning av kupé och batteri samt en PTC (elektrisk värmare) för uppvärmning av detsamma. LÄS MER

  7. 5. Preliminary Design of a 30 kN Methane-Oxygen-powered Electric-Pump-fed Liquid Rocket Propulsion System

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Vikramjeet Das; [2023]
    Nyckelord :rocket engine; liquid rocket; methalox; electropump; LRPS; LPRE; liquid methane; electric pump feed system;

    Sammanfattning : The design of a liquid rocket propulsion system, unlike that of a standalone system, is intertwined with the overall development of a number of associated systems and is influenced by a multitude of conditions and considerations: from the requirements needed to accomplish the mission to the rationalizations involved behind the development of each rocket system and/or component. In my thesis, the preliminary design of a “new generation” 30 kN rocket engine driven by an electric pump feed system and running on liquid methane and liquid oxygen is performed. LÄS MER
