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

3. 2. A comparison of pressurised cylinders in HIP systems using CFD and FEM

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

   Author : Lisa Lindqvist; [2021]
   Keywords : Hot isostatic pressing; HIP; Pressure vessel; Monoblock; Axisymmetric; FSI;

   Abstract : A hot isostatic press (HIP) is a system which utilises high temperatures and pressure in order to densifyand enhance the material properties of components in the aerospace, automotive and additive manufacturingindustries, to mention a few. Quintus is a world leading manufacturer of HIP systems, and this master’s thesiswork has been written in collaboration with them. READ MORE

4. 3. 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

5. 4. 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. 5. 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.
