  1. 1. 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

  3. 2. New process for leak detection in truck pneumatic systems during production using an ultrasound camera

    University essay from Uppsala universitet/Industriell teknik

    Author : Henrik Gustafsson; Malva von Schenck; [2023]
    Keywords : industry; leak detection; leak positioning; pneumatic system; pressure drop test; production; quality assurance; ultrasound camera;

    Abstract : The process of producing compressed air in the industry today is highly energy inefficient. Up to 75 % of the energy spent on producing compressed air to the compressed air systems (CASs) is wasted. Out of the produced air, 24 % is wasted due to air leaks. READ MORE

  4. 3. Accelerated Testing of the End-plate Assembly of a Redox Flow Battery

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

    Author : Saksham Jindal; [2022]
    Keywords : Energy Storage; Flow Batteries; Accelerated Testing; Contact Resistance; Endplate Assembly; Leak Rate; Stack Design; Energilagring; flödesbatterier; accelererad provning; kontaktmotstånd; montering av ändplattor; läckagehastighet; utformning av staplar.;

    Abstract : As the world transitions to intermittent renewable energy sources like solar and wind, the need for long-duration energy storage technologies is becoming more and more prominent. In this regard, flow batteries are seen as a promising solution, owing to their inherent advantages like decoupling of power and energy, extremely high cycle life and negligible self-discharge.

  5. 4. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Alejandra Fernandez Castaneda; [2022]
    Keywords : Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Abstract : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).

  6. 5. Flow data based leak detectionfor underdetermined water networks

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Yashaswini Seeta; [2021]
    Keywords : ;

    Abstract : Water leaks are a common and wasteful occurrence in all Water Distribution Networks (WDNs). There has been extensive research for detecting and localizing leaks. However, an overwhelming number of these techniques use both pressure and flow of the WDN. READ MORE
