  1. 1. 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.

  3. 2. HSI effects on pedestrian bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Giancarlo Costa; [2021]
    Keywords : Dynamics; HSI; Human Structure Interaction; pedestrian bridge;

    Abstract : The study on Human Structure Interaction (HSI) effects represent a new research field in the design of pedestrian bridges. The presence of pedestrians on the structure affects the dynamic properties of the bridge, and these changes may be quantified in order to design pedestrian bridges in a more efficient way.

    University essay from KTH/Bro- och stålbyggnad

    Author : Sara Ahmadiyan; Daniel Mehari; [2021]
    Keywords : existing; structures; characteristic; in-situ; compressive; non-destructive; semi-destructive; destructive; cores; EN13791; GCSC; TDOK; UPV; Rebound; Pull-out; Windsor; correlation; calibrate; indirect; direct; estimate; befintlig; konstruktion; karakteristisk; tryckhållfasthet; icke-destruktiv; halv-destruktiv; destruktiv; kärnor; EN13791; GCSC; TDOK; UPV; Rebound; Utdragskraft; Windsor; korrelation; kalibrera; indirekt; direkt; bedöma;

    Abstract : It is inevitable that Structures become older and their intended use changes or the structuralcodes regulations change. In some regions the damage from seismic activities is a possibility.It becomes, therefore crucial to assess the structural capacity of such structures. READ MORE

  5. 4. 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

  6. 5. Non-Destructive Testing Of Concrete Bridges

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Nadja Hedlund; [2020]
    Keywords : Non-Destructive testing; Concrete; Covermeter; Ultra-Sonic Pulse Velocity; Rebound hammer;

    Abstract : Non-destructive testing is of great value in cases where a structure's future is investigated to find out what the best measure is. It is not always the best solution to demolish and build new. Many structures can be repaired and function several more years. READ MORE
