  1. 21. Additively Manufactured Heat Exchangers- Development and Testing

    University essay from Lunds universitet/Innovation

    Author : Isak Wadsö; Simon Holmqvist; [2020]
    Keywords : Additive manufacturing; Heat exchanger; Triply periodic minimal surface; AlSi10Mg; Technology and Engineering;

    Abstract : Heat exchangers are important devices in many applications. Extensive work is done in optimization, but the overall designs are often one of the conventional varieties such as plate or shell-and-tube heat exchanger. These are constrained by their manufacturing, for example the use of construction material such as sheet metal and cylindrical pipes. READ MORE

  2. 22. Aqua Ammonia as Secondary Fluid in Ice Rink Applications

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

    Author : Brianna Kilberg; [2020]
    Keywords : Ice rink; secondary fluid; aqua ammonia; ammonia water; thermophysical properties; corrosion; pressure drop; pumping power; refrigeration;

    Abstract : Refrigerant management is crucial in the attempts to slow climate change. Emissions from the refrigeration sector are primarily due to poor management and unsafe destruction of refrigerants currently in circulation. Safe refrigerant management and improving system operating efficiency can result in a reduction of emissions. READ MORE

  3. 23. Dimples in corrugated channels to improve efficiency in plate heat exchangers

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gustav Karlsson; [2020]
    Keywords : Dimples; Plate Heat Exchangers; Heat Transfer Enhancement; CFD; Large Eddy Simulation; Reynolds Averaged Navier Stokes Simulation; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : The development of new heat exchanger patterns is ever changing. Companies are constantly pushing innovation to satisfy costumer needs in terms of thermal efficiency, reliability and serviceability. In this thesis, the implementation of dimples in the corrugated pattern of a plate heat exchanger is investigated to increase the thermal efficiency. READ MORE

  4. 24. Systematic optimisation of an existing fuel oil preheating system : Facilitating replacement of 5000 cSt oil with 74 500 cSt

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Albin Fransson; Peter van der Brug; [2020]
    Keywords : Heat Exchanger; Shell; Tube; Plate; DFSS; Fuel Oil; Optimisation; Viscosity; Efficiency;

    Abstract : In order to increase the efficiency of a preheating system as temperatures increase, without using seawater as a coolant, an additional heat exchanger is required to be installed into the system. The purpose of the study is therefore to investigate how the temperatures of fuel oils can be increased while minimising the loss of energy and costs. READ MORE

  5. 25. Conceptual design and development of thermal management system for hybrid electric aircraft engine. : A study to develop a physical model and investigate the use of Mobil Jet Oil II as coolant for aircraft electrical propulsion under different scenarios and time horizons.

    University essay from Mälardalens högskola/Framtidens energi

    Author : Yash Khanna; [2019]
    Keywords : Hybrid electric aircraft system; Thermal management system; micro channel; Dynamic modelling; Mobil Jet Oil II;

    Abstract : The ever-increasing levels of greenhouse gas emissions has led to the scientific community starting to explore the viability of electrical aircraft system, with the most prominent research and product development for hybrid electric system, which forms the transition phase from combustion to fully electric aircrafts. The primary objective of this thesis is to find solutions towards thermal management of the electrical components of a hybrid electric aircraft propulsion system, which generate a significant amount of heat while operating at heavy load conditions required to propel an aircraft.
