  1. 1. Design and investigation of a pulsating heat pipe for electronic cooling

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Sulafa Hammad; [2023]
    Nyckelord :Pulsating heat pipes PHP ; Electronic cooling; two phase flow heat transfer; Technology and Engineering;

    Sammanfattning : The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. LÄS MER

    Sammanfattning : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. LÄS MER

  5. 4. Modeling and optimisation of a rotary kiln reactor for the processing of battery materials

    Master-uppsats, KTH/Kemiteknik

    Författare :Danial Khawaja; [2021]
    Nyckelord :Granular flow; rolling mode; suspension model; two-fluid model; multiphase flow; Granulärt flöde; rullningsläge; suspensions modell; tvåvätskemodell; flerfasmodell;

    Sammanfattning : Roterugnar är cylindriska kärl som används för att höja materials temperaturer i en kontinuerlig process som kallas för kalcinering. Roterugnar kan tillämpas i olika processer såsom reduktion av oxidmalm samt återvinning av farligt avfall. LÄS MER

  7. 5. CFD Simulation of a Fin-Tube Evaporator under icing

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Abhay Mahesh Hervatte; [2021]
    Nyckelord :CFD; Refrigeration; HVAC; Evaporator; Thermodynamics; Icing;

    Sammanfattning : The study involves development of a methodology to simulate a fin-tube evaporator under icing conditions using CFD in Ansys® Academic Fluent 2021R1. It aims to build on previous studies performed on heat pumps. It was performed by Abhay M. Hervatte in collaboration with Bosch Thermoteknik AB, Tranås, SE during the spring term of the year 2021.
