1. Evaluating the Performance of Propulsion System Elements in an Aerospace Company
University essay from KTH/Kraft- och värmeteknologiAbstract : 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. READ MORE

2. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV
University essay from Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)Abstract : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV). I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri. READ MORE

4. Controls of seafloor depth on hydrothermal vent temperatures : prediction, observation & 2D finite element modeling
University essay from Lunds universitet/Geologiska institutionenAbstract : Circulation of hot hydrothermal fluids in fractures and faults of the oceanic crust is driven by temperature and pressure gradients. Fluid discharge is focused to vertical structures, black or white smoker chimneys on the seafloor. Hydrothermal vent temperatures should hypothetically be directly related to water depth. READ MORE

5. Effects of Upwelling Events on the Atmosphere
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : During an upwelling event the cold bottom-water is brought to the sea surface. This cools the atmosphere from below and the stratification becomes more stable. When the atmosphere is more stable the turbulence is reduced and, as a consequence, so are the turbulent fluxes.
