  1. 1. Evaluating sensor accuracy and repeatability in gasketed plate heat exchangers

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Nils Engman; [2023]
    Keywords : Sensors; IoT; Heat Exchangers; Technology and Engineering;

    Abstract : Alfa Laval has connected sensors to their gasketed plate heat exchangers (gphe) to extend their customer service offering. To develop this service further the flow through the GPHE is needed. In this thesis, the objective was to evaluate an inexpensive flow switch and two sensor kits that measure pressure and temperature. READ MORE

  3. 2. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Fritjof Nilsson; Yanjun Peng; [2023]
    Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

    Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

  4. 3. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

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

    Author : WULLSCHLEGER LÉA; [2023]
    Keywords : Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Abstract : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. READ MORE

  5. 4. Dynamic Modeling of Heat Power System : Modeling of a Heat Power System Using Physical and Data-driven Methods and Investigation of a Moving Boundary Method

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Albin Gustafsson; [2023]
    Keywords : System identification; Dynamic modeling; Organic Rankine cycle; Moving boundary; Thermodynamics.; System identifikation; Dynamisk modellering; Organisk Rankinecykel; Rörliga randvillkor; Termodynamik.;

    Abstract : Our society is becoming more and more electrified every day. However, a significant portion of the world’s electricity generation relies on the combustion of fossil fuels to produce heat, which is subsequently harnessed to generate electricity. One way of generating electricity from heat is by utilizing a Rankine cycle. READ MORE

  6. 5. Dimensioning study of EPR2 fuel pool cooling system

    University essay from KTH/Fysik

    Author : Thomas Rubler; [2023]
    Keywords : EPR2; PTR; spent fuel pool; heat exchange; EPR2; PTR; bassäng för utbränt kärnbränsle; värmeväxling.;

    Abstract : The PTR system allows the EPR2 fuel pool to be cooled. The evacuation of the residual power fromthe pool is ensured by several heat exchangers and pumps, which have to be dimensioned in order to meetdifferent requirements.In order to dimension them, the worst-case scenario of the components must first be determined.
