  1. 11. 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.

  6. 15. Master Thesis - Towards a Virtual Climate Chamber : A numerical study using CFD software

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Yuvarajendra Anjaneya Reddy; [2020]
    Keywords : CFD; Ansys FLUENT; Power Spectral Density; Turbulence quanitification; Digital Twin;

    Abstract : For each generation of electronic equipment there is a trend towards higher power den-sities. Increased heat generation is an undesired consequence that the thermal design unit in a company must handle. The goal of thermal design engineer/unit is to utilizethe same volume to more efficiently transfer more heat from the equipment. READ MORE
