  1. 6. Experimental pressure loss analysis in a mini tube for a fully developed turbulent airflow. : Mini channels of lengths 22.5 mm to 150 mm in length with a constant diameter of 1.5 mm

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Soumen Ghosh; [2022]
    Keywords : Experimental fluid mechanics; Pressure drop; friction factor; Internal flow; fully developed flow; turbulent flow; Fluid mechanics; Ideal gas; Moody s chart; Additive manufacturing; compressible flow; turbine blade cooling; mini channel;

    Abstract : The cooling systems in a gas turbine are especially important as the turbine blades and vanes are exposed to extreme temperatures. The relatively cool air is extracted from the compressors and fed to the turbines to cool the turbine blades. READ MORE

  2. 7. LES modelling of spray combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Arvid Åkerblom; [2021]
    Keywords : Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

    Abstract : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

    Abstract : In recent years, the increasing economic, environmental and legal demands on internal combustion engines to reduce emissions and fuel consumption are a major challenge. A lot of effort has been put into achieve reliable methods of diagnosis, fault detection and monitoring to increase safety and efficiency in vehicles. READ MORE

  4. 9. Performance Investigation & Gas Exchange Assessment of Exhaust Piston–assisted Turbocharged Engine (EPTE) Concept : A simulation-based assessment

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Nachiketh Lingachari Acharya; Saurav Dasgupta; [2021]
    Keywords : ;

    Abstract : There is an increasing stringency in the emission legislation within the transport industry along with ambitious performance demands from the customer side. These have pushed the vehicle manufacturers and relevant component suppliers to develop and integrate a wide portfolio of engine technologies. READ MORE

  5. 10. External Heat Transfer Coefficient Predictions on a Transonic Turbine Nozzle Guide Vane Using Computational Fluid Dynamics

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Daniel Enico; [2021]
    Keywords : CFD; LS89; transonic turbine; transition; transition model; turbulence decay; turbulence intensity; length scale; turbulence characteristics; HTC; external heat transfer coefficient; Steelant-Dick postulation;

    Abstract : The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. READ MORE
