  1. 1. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sanger Shinwari; [2023]
    Keywords : Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

    Abstract : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. READ MORE

  2. 2. Formula Student Car Stability

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Oliver Belfiore; [2023]
    Keywords : Racing; Car; Vehicle; dynamics; vehicle dynamics; Technology and Engineering;

    Abstract : This thesis investigates the impact of varying passive components on the stability of a Formula Student race car. The study was conducted using a 7-post model and a lateral model, both of which were derived using Lagrangian methods and state-space modelling techniques. These models were then validated and adjusted using logged data. READ MORE

  3. 3. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Gustav Blomgren; Ebba Carlsson; [2023]
    Keywords : Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

    Abstract : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. READ MORE

  4. 4. Simulation based optimizing of fog mesh structures for enhanced fog collection

    University essay from KTH/Teknisk mekanik

    Author : Jiawei Miao; [2022]
    Keywords : ;

    Abstract : Water scarcity has been an increasing problem in many places around the world. According to the World Resources Institute, in 2019 nearly 2.6 billion people which takes a third of the world's population live in the area with 'high water scarcity', with 1.7 billion people in 17 countries living under 'extreme water scarcity'.

  5. 5. Signatures of Dark Matter at the LHC : A phenomenological study combining collider and cosmological bounds to constrain a vector dark matter particle model

    University essay from Uppsala universitet/Högenergifysik

    Author : Anton Olsson; [2022]
    Keywords : Dark matter; particle phenomenology; LHC; MadGraph; standard model; beyond standard model;

    Abstract : Everything that humans have ever touched, created or built something from consists of a type of matter that only makes up 15 percent of the total matter in the universe. The remaining 85 percent is attributed to dark matter, a so far not discovered and non-luminous type of matter. READ MORE
