1. 1. Increase of biogas production by incorporating residual streams from agriculture

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Stephanie Fjäll; [2022]
   Keywords : Anaerobic digestion; Agricultural residue; Lignocellulosic biomass; Mechanical pretreatment; Biogas production; Biorefinery; Chemical engineering; Agriculture and Food Sciences; Technology and Engineering;

   Abstract : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. READ MORE

3. 2. Co-Simulation Development for Improved Cavitation Predictions in Oil-Hydraulics Systems : An investigation into the cavitating flow behavior of repetitive water hammers.

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Thisal Mandula Sugathapala; Twan Bakker; Rahul Gudur Suresh; Aryan Delir; [2022]
   Keywords : co-simulation; water hammer; cavitation;

   Abstract : Numerical modeling of cavitation using computational software is a highly pursued topic of research due to its impact in different industrial sectors. While some industrial applications such as wastewater treatment and mineral processing are known to advantageously use this phenomena, it remains an unwanted process in others where it is known to induce vibration, reduce performance and cause structural damage.

4. 3. Cavitation analysis on test rig. : An experimental and CFD study executed in collaboration with Epiroc AB

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Oskar Kuoppala; [2021]
   Keywords : CFD; Cavitation; Water Hammer;

   Abstract : This master thesis project was done in collaboration with Epiroc Group Ab. Epiroc supplies high-quality drills of various types that can be used both above and below ground. A major problem in their percussive rock drills is that that cavitation is formed. Cavitation is a phenomenon that occurs when a fluid is subject to a sudden pressure drop. READ MORE

5. 4. Modelling of high-pressure fuel system for controller development

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Eric Pettersson; [2019]
   Keywords : Common-Rail Direct Injection; fuel system; water hammer; pressure oscillations; physical modelling; state-space representation;

   Abstract : This master thesis treats the modelling of a common-rail direct fuel injection system where pressure generation is decoupled from the injection process. It has been shown that the fuel pressure plays a vital role for the general performance of the engine, affecting both emissions and efficiency, and it is carefully regulated to achieve optimal performance at different operating points.

6. 5. Ram pump hydraulic air test. Pressure conditions and flow measurements: Experimental research and case study

   University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

   Author : Paula María Arizcun Zúñiga; [2018]
   Keywords : Ram pump; water hammer; pressure; efficiency; installation; drive pipe; delivery pipe; impulse valve;

   Abstract : This study consists of the development of a ram pump, which will allow the pumping of water without the need of external energy sources. It is considered an analysis of interest since, once it is finished; it can be applied in reality improving and facilitating different activities related to agriculture and health. READ MORE
