1. 16. CO2 Refrigeration withIntegrated Ejectors : Modelling and Field Data Analysis ofTwo Ice Rinks and Two Supermarket Systems

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

   Author : SIMON FEHLING; [2021]
   Keywords : Vapor Ejector; Liquid Ejector; Field Data Evaluation; Modelling; Refrigeration; CO2; Ice Rink; Supermarket; Heat Recovery; Ångejektor; Vätskeejektor; Fältmätdata; Modellering; Kylteknik; CO2; Isbana; Livsmedelsbutik; Värmeåtervinning;

   Abstract : With the increasing importance of CO2 as natural refrigerant with low Global Warming Potential(GWP) ejectors have been used in a number of recent installations to recover expansion work atthe high operating pressures of these systems. In colder climates, this is particularly seen in combinationwith heat recovery due to the high compressor discharge pressures. READ MORE

3. 17. Design and Optimisation of Internal Components for a Reciprocating Compressor Powering a Camless Valvetrain

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Filip Schander; Viktor Pott; [2021]
   Keywords : Topology; FEA; DMLS; Piston; Connecting Rod; Crank Mechanism; Crank Balancing; Technology and Engineering;

   Abstract : Freevalve AB develops camless valvetrains for internal combustion engines using pneumatic and hydraulic systems. An air compressor is used to generate pressure in the pneumatic system. To further increase efficiency of the Freevalve system, a new compressor tailored to its purpose, is being developed in house. READ MORE

4. 18. Design of an In-situ cell, for hard X-ray spectroscopy of surfaces used in high-pressure and high-temperature experiments : Design av en In-situ cell för intensiv röntgenspektroskopi i högtryck- högtemperaturexperiment

   University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

   Author : David Zamora Torres; Felix Abeln; [2021]
   Keywords : In-situ cell; x-ray; XAS; x-ray absorption spectroscopy; XAFS; FEM; Finite element method; In-situ cell; x-ray; XAS; XAFS; FEM; Finita element metoden; röntgenspektroskopi;

   Abstract : This project analyzes how an in-situ cell can be developed to withstand high amounts of pressure and temperature of at least 100 bar and 500 °C. A theoretical prototype will be created as a product for Malmö University and other researchers to use or improve. READ MORE

5. 19. Electrically powered manoeuvring of water jets

   University essay from Uppsala universitet/Industriell teknik

   Author : Joel Engström; [2021]
   Keywords : Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

   Abstract : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.

6. 20. Feasibility of Enhanced Geothermal Systems in the Precambrian crystalline basement in SW Scania, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Hanna Kervall; [2021]
   Keywords : EGS; deep drilling; geothermal; petrology; petrophysical properties; Sveconorwegian; Earth and Environmental Sciences;

   Abstract : The ability to evaluate the geothermal potential at a depth of five to six kilometres in the crystalline bedrock is crucial for the EGS-technology to be utilized in the future. This work focuses primarily on presenting expected geological conditions at great depths in southwestern Scania. The study is based on information from E. READ MORE
