1. 1. Techno-economic analysis and simulation of low temperature district heating networks

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Ilia Iarkov; [2023]
   Keywords : Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

   Abstract : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. READ MORE

3. 2. Evaluating the Performance of Propulsion System Elements in an Aerospace Company

   University essay from KTH/Kraft- och värmeteknologi

   Author : David Fredouelle; [2023]
   Keywords : Turbomachinery; injector; test campaign; cryogenic; rocket engine; test bench; cold flow; Turbomaskin; injektor; testkampanj; kryogen; raketmotor; testbänk; kallt flöde;

   Abstract : This paper examines two examples of testing activities of sub-components of a 300kN methalox first-stage rocket engine developed by Pangea Aerospace, namely, theinjectors and the cryogenic pumps. One of the difficulties of these test campaignsis to evaluate the performances of these sub-components without using cryogenicpropellants and in conditions differing from flight conditions.

4. 3. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
   Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

   Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

5. 4. Design of a vacuum chamber for cathode testing and low power Hall Effect Thrusters : Collaborative project with OHB Sweden AB

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

   Author : Andrea Martinez Sanz; [2023]
   Keywords : Vacuum chamber; adaptability; hollow cathode test; fluid ground support equipment; low power Hall Effect Thrusters test; Vakuumkammare; anpassningsförmåga; ihålig katod testa; flytande markstödutrustning; låg effekt Hall Effect Thrusters testa;

   Abstract : Testing of hardware to be used in space sometimes involves using vacuum chambers. The need to test hollow cathodes, used as neutralizers for some Electric Propulsion Thrusters, and low power Hall Effect Thrusters at OHB Sweden requires a vacuum chamber to be upgraded. READ MORE

6. 5. Modeling for characterization of continuous casting simulator using CFD

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Filip Reineholm-Hult; [2023]
   Keywords : Continuous casting; CFD; computational fluid dynamics;

   Abstract : In order to improve the continuous casting process of steel, it’s important to have an understanding of the fuid mechanics of the casting process. As experiments on a real caster are usually impractical, both physical and numerical modeling are important for creating this understanding. READ MORE
