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

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

  3. 2. Study of high flash point ethyl alcohol-based secondary fluids applied in Ground Source Heat Pumps systems

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Keywords : indirect refrigeration system; secondary fluid; flammability; alcohols; geothermal heat pump systems; properties.;

    Abstract : Ethyl alcohol (ethanol) as secondary fluids is very popular as heat transfer fluid for indirect refrigeration system with ground source heat pump systems (GSHP) in several countries such as Sweden, Norway, Switzerland, Finland and other European countries. There have been several researches about the future ofthe refrigeration sector, refrigerants and refrigeration systems. READ MORE

  4. 3. Techno-Economic Analysis of Organic Rankine Cycles for a Boiler Station : Energy system modeling and simulation optimization

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Jamel Hudson; [2019]
    Keywords : Organic Rankine cycle; ORC; Working fluids; Boiler station; District heating system; Simulation model;

    Abstract : The Organic Rankine Cycle (ORC) may be the superior cycle for power generation using low temperature and low power heat sources due to the utilization of high molecular mass fluids with low boiling points. They are flexible, simple, easy to operate and maintain, and offer many possible areas of applications including waste heat recovery and power generation from biomass, geothermal and even solar energy.
