1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Shivang Parmar; [2023]
   Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

   Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE

3. 2. 3D CFD Simulations of Hydrogen Engine Combustion

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Hao Liu; [2023]
   Keywords : Technology and Engineering;

   Abstract : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. READ MORE

4. 3. 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

5. 4. Tether-free Driveline Control for Water Propulsion Devices

   University essay from Lunds universitet/Ergonomi och aerosolteknologi; Lunds universitet/Certec - Rehabiliteringsteknik och Design

   Author : Isak Marklund; Axel Müller; [2023]
   Keywords : Dead man’s switch; electric surfboard; jet surfboard; machine learning; user experience; usability testing; neural network; decision tree; bootstrap aggregating; time series; Technology and Engineering;

   Abstract : For many machines, safety requires the constant presence of an operator, with the risk of damage or danger if the operator is unintentionally absent. Dead man’s switches (DMS) are commonly used to halt operations if this absence is detected, often relying on physical elements like leashes or buttons. READ MORE

6. 5. Numerical study of a jet impacting a heated object

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Moutaz Hammoud; [2023]
   Keywords : Numerical model; COMSOL Multiphysics; Heat transfer; Impinging jets.;

   Abstract : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. READ MORE
