1. 11. Predictive Maintenance for RM12 with Machine Learning

   University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Author : Lotta Karlsson; [2020]
   Keywords : ;

   Abstract : Few components within mechanical engineering possess the fatigue resistance as of high-pressure turbine blades found in jet engines. This as they are designed to perform in extensively high temperatures under severe loading which causes degradation to be an important aspect despite a design, optimized for its environment.

   Abstract : Combustion of fossil fuels is the most important energy source today. Burning fossil fuel is however expensive and bad for the enviroment. Improving the combustion technology to reduce fuel consumption, and to be able to burn renewable fuels is therefore of great importance. READ MORE

5. 14. Tribology of newly developed EAL versus water in hydropower turbine bearings

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

   Author : Nayan Dhakal; [2019]
   Keywords : water-based lubrication; hydropower; turbine bearings; environmentally adaptive lubricants; modified water; viscosity modifiers; polyvinylpyrrolidone; poly sodium 4-styrenesulfonate ; UHMWPE; wear;

   Abstract : The increasing demand for more readily bio-degradable, renewable and non-toxic environmentally adaptive lubricants with a lower degree of bioaccumulation has escalated the investigation of water-based lubricants as the potential alternatives for conventional mineral-based oils. Water is an excellent environmentally adapted lubricant; however, it is a low viscous fluid and holds downsides of having corrosive nature and extremely low pressure-viscosity coefficient leading to insufficient load-carrying capacity.

6. 15. Investigation of a CO-Production of Substitute Natural Gas and Biomethanol Plant Compared to Stand Alone Biomethanol Plant

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Susanne Brixland; [2019]
   Keywords : biomethanol; SNG; substitute natural gas; co-production; gasification; gasifier; biomass; syngas; chemical engineering; kemiteknik; Chemistry; Technology and Engineering;

   Abstract : Climate change is one of humanities greatest challenges; the greenhouse gases in the atmosphere are still increasing. There is not one solution that will fix this problem several different products, raw material and technologies are required to take the steps towards a renewable society. READ MORE
