1. 21. Techniques to inject pulsating momentum

   University essay from Luleå tekniska universitet/Strömningslära och experimentell mekanik

   Author : Jelle Kranenbarg; [2020]
   Keywords : Hydro power; Rotating Vortex Rope; Flow control; Fluidic actuator; Synthetic jet actuator; Piston actuator; CFD;

   Abstract : Hydro power plants are an essential part of the infrastructure in Sweden as they stand for a large amount of the produced electricity and are used to regulate supply and demand on the electricity grid. Other renewable energy sources, such as wind and solar power, have become more popular as they contribute to a fossil free society. READ MORE

3. 22. Pressurizing of high-pressure fuel system forsingle cylinder test cell

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Gustaf Glaad; [2019]
   Keywords : Alternative fuels; Ultra high-pressure fuel system; Common rail direct injection fuel system; Diesel-like fuels; Compression ignited fuels;

   Abstract : This master thesis covers the development of a high-pressure fuel system for compression ignitedfuels such as diesel and diesel-like fuels that will be deployed into a single cylinder test cell at AVLMTC Södertälje, Sweden. The test cell is used by AVL to conduct research and testing of new fuelsfor their customers and this new fuel system will widen the span of fuels able to be tested by theequipment. READ MORE

4. 23. Calibration and Validation of Efficient Combustion and EmissionModels for 3D-CFD EngineSimulations

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Vikas Shettihalli Anandreddy; [2019]
   Keywords : ;

   Abstract : To accurately analyze combustion and emissions in the internal combustion engine, hundreds of chemical species have to be transported in the computational domain in the form of a detailed chemical mechanism. The use of this detailed chemical mechanism in the computational domain leads to an increase in computational time. READ MORE

5. 24. Evaluation of a digitial displacement pump in a load haul dump application

   University essay from Linköpings universitet/Fluida och mekatroniska system

   Author : Jayasurya Madhusudanan; [2019]
   Keywords : Digital displacement pump; mine loader; energy efficiency; backward simulation; forward simulation; pump losses;

   Abstract : Hydraulics has always been the first choice of actuation in off-road, construction and mining vehicles due to its power density, low cost, built in cooling and lubrication. However, the current state of our environment along with stricter regulations has brought light to newer technologies within hydraulics to improve the existing system. READ MORE

6. 25. Full Cycle Cylinder State Estimation in DI Engines with VVA

   University essay from Linköpings universitet/Fordonssystem

   Author : Linus Johansson; [2019]
   Keywords : VVT; Combustion engine; Thermodynamics; CRB;

   Abstract : Tougher legal demands on pollutions require a better developed understanding of the processes that take place in the cylinder. The thesis contributes with a cylinder model that uses the same set of equations for intake, compression,expansion/combustion and exhaust. READ MORE
