  1. 16. 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.

  2. 17. Development of a CFD Boundary Condition to Simulate a Perforated Surface

    University essay from Umeå universitet/Institutionen för fysik

    Author : Medet Kiflemariam; [2021]
    Keywords : Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

    Abstract : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.

  3. 18. A COMPARATIVE STUDY OF TRAVELLING FIRE IN LARGE SPACES WITH MULTI-ZONE FIRE MODEL AND FDS

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Paolo Bertoli; [2021]
    Keywords : Multi-Zone fire model; FDS; Large enclosures; Travelling fire.; Technology and Engineering;

    Abstract : A knowledge of far field temperatures is valuable for Performance Based Design structural analysis and life safety analysis, where a parametric study is needed. A fire model using multiple zones called a multi zone (MZ) fire model has in previous studies shown good potential as an analytical tool for predicting far field temperatures in large compartments.

    Abstract : This study was performed to investigate aerodynamic characteristics of the 37.5% scaled­ down Green Raven MK18 airframe, to evaluate boundary corrections method, and to investigate on support interference. READ MORE

  5. 20. High Altitude Glider Solution for Returning From Space

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jakob Nylöf; Koray Amico Kulbay; [2021]
    Keywords : Aerodynamics; aeronautics; gliding flight; nearearth space research; sounding rocket; KTH; REXUS; XFLR5; Simscale; CFD;

    Abstract : Space exploration drives the human expansion inthe universe. Succeeding in this challenge demands familiarityof the near earth space environment, achieved through soundingrocket experiments that often are lost upon return from space. READ MORE
