  1. 16. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Rosalie Johnsson; Lilian Asiegbu; [2022]
    Keywords : gas turbine; turbine inlet guide vane; film-cool; film cool; Computational Fluid Dynamics; CFD; heat transfer coefficient; Shear Stress Transport k-ω; SST k-ω; Scale Resolving Hybrid; SRH; turbulence modelling;

    Abstract : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. READ MORE

  3. 17. CONTROL STRATEGY AND MODELING FOR ENGINE OIL SYSTEM

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Dalibor Colic; Jakob Norin; [2021]
    Keywords : ;

    Abstract : The power of an engine is not only used to drive the mechanical equipment connected to the engine, but also parts of the engine itself. One of these parts is the oil pump. The minimum needed oil pressure, produced by the pump, varies during the operational run of the engine. READ MORE

  4. 18. Role of damping in NVH CAE procedures

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Rahul Sharma; [2021]
    Keywords : NVH; CAE; Damping;

    Abstract :   Automotive manufacturers currently face a challenge with expeditious enhancement of the vibro-acoustic properties of their vehicles. A major reason for this setback is the limited design information available during initial development stages added with limited knowledge of damping within complex structures. READ MORE

  5. 19. Grey Box Model of Leakage In Radial Piston Hydraulic Motors

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

    Author : Niklas Ydebäck; [2021]
    Keywords : Grey box; modeling; Radial piston; Bosch Rexroth; parameter estimation;

    Abstract : This report covers the work and results of the thesis project in Mechanical Engineering from Luleå university of technology performed by Niklas Ydebäck. The objective of the thesis project is to research if it is possible, with general principles of fluid flow between components and the corresponding geometric constraints between them and just a few channels of data, to model the leakage of a radial piston hydraulic motor.

  6. 20. Plasma Burner: Numerical Modeling of Plasma Generation and Flow

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Julian Colmenares; Diyar Ghazi; [2021]
    Keywords : Plasma physics; Energy; Space technology; Fluid flow; Plasma burner; Plasma generator; Fossil free industry; Comsol multiphysics; Simulation; Modeling;

    Abstract : Technological evolution and mass production is impacting the Earth daily due to global warming caused by greenhouse gas emissions, where the biggest factor is the emission of carbon dioxide mostly caused by the burning of fossil fuel and industrial processes. Therefore, alternatives for substituting the use of fossil fuel in industries are extremely important. READ MORE
