  1. 1. Feasibility study on Thermal Anemometry at LWR conditions

    University essay from KTH/Fysik

    Author : Abishek Baskar; [2021]
    Keywords : Nuclear Enginnering; Thermal-Hydraulics; Instrumentation; Material technology; Fluid Dynamics. Light water reactors;

    Abstract : Dryout and Departure from Nucleate boiling (DNB) are utmost thermal-hydraulic concerns for the safety of LWRs. The behavior of two-phase flows at these conditions is still not fully understood. There is at least a need for a good local velocity and void fraction database at these conditions. READ MORE

  2. 2. Heat Transfer Analysis on the Applications to Heat Exchangers

    University essay from

    Author : Raghu Lakshman Gundra; Jagadeesh reddy Medapati; [2021]
    Keywords : CFD anlysis; Heat exchangers; Heat transfer analysis; Heat equation temperature; Temperature equilibrium.;

    Abstract : A heat exchanger is a device used to transfer thermal energy between two or more fluids, at different temperatures in thermal contact. They are widely used in aerospace, chemical industries, power plants, refineries, HVAC refrigeration, and in many industries. READ MORE

  3. 3. 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.

  4. 4. 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.

  5. 5. 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.
