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. CFD investigation of a unit cell inside a Plate Heat Exchanger

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Mattias Ly; [2023]
   Keywords : Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

   Abstract : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. READ MORE

5. 4. Investigation of Manufacturing Method for Odd-holed Plates for Gasketed Plate Heat Exchangers

   University essay from Lunds universitet/Industriell Produktion

   Author : Hanna Eklind; Johanna Schedin; [2023]
   Keywords : manufacturing methods; punching with eccentric presses; abrasive water jet cutting; laser cutting; Technology and Engineering;

   Abstract : Den här rapporten undersöker samt jämför det möjliga användandet av olika tillverkningsmetoder i produktionen av varianthålade plattor vid Alfa Lavals produktion i Lund. De tre metoderna är stansning med excenterpressar, abrasiv vattenskärning och laserskärning, där de två förstnämnda används i Alfa Lavals produktion i dagsläget. READ MORE

6. 5. Full Material Declaration - A case study on the readiness for declaring Full Material Declaration of chemical substances in components, used in finished products

   University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

   Author : William Lövdahl; [2022]
   Keywords : full material disclosure; full material declaration; FMD; chemical substances in products; CiP; information flow in supply chain; chemical declaration; information flow; chemical; mapping chemical substances; tracking chemical substances; transparency in the supply chain; supplier data sharing; readiness and chemical management; chemical management; chemical disclosure; Earth and Environmental Sciences;

   Abstract : The production and use of chemicals has grown exponentially over the past 50 years. Although the knowledge of hazards and risks associated with chemicals towards humans and the environment has increased, we know frightenedly little about how dangerous these might become when part of finished products.
