  1. 6. An analytical method for quickly evaluating the performances of refractory alloys in sCO2 Brayton cycle applications

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

    Author : Jiaqi Yang; [2023]
    Keywords : ;

    Abstract : A rapid and effective analytical method has been developed to assess the performance of structural materials in sCO2 power cycle applications. This method combines a conjugate heat transfer model, considering constant heat flux boundary conditions, with a corresponding mechanical model. READ MORE

  3. 7. Simulation of Combustion in a Hybrid Rocket Engine

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oscar Andersson; [2023]
    Keywords : Thesis; Hybrid Rocket Engine; CFD; computational fluid dynamics; combustion;

    Abstract : A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant. READ MORE

  4. 8. Testing of AblativeMaterials as a Protective Coating for Rocket Launch Pads

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

    Author : Gioele Daka; [2023]
    Keywords : Ablative Materials; Protective Coating; Rocket Launchpad; Refractory Materials; Oxyacetylene Torch; Slug Calorimeter; Ablativa material; Skyddande beläggning; Raketstartplatta; eldfast material; acetylensyrebrännare; kopparkalorimeter;

    Abstract : As the space market grows, demand for sites to host rocket tests and to launch satellites to orbit is expected to increase. During these activities, the launch infrastructure needs to withstand the extreme thermal and mechanical loads associated with the exhaust of a rocket engine. READ MORE

  5. 9. Mitigating Post-Harvest Losses in Bhutan through Solar Food Drying: Optimization and Analysis

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Christian Rissler; [2023]
    Keywords : Solar dryer; Ginger; Drying; Bhutan; Heat exchanger; Heat storage; Solar absorber; Drying rate; Air flow; Technology and Engineering;

    Abstract : Bhutan is the world’s most mountainous country which comes with some logistical difficulties. Due to slow transportation times and lackluster food preservation are the post-harvest losses high which especially affects the rural parts of Bhutan negatively. READ MORE

  6. 10. Solving Korteweg-de Vries equations with Discontinuous Galerkin methods

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Markus Hellberg Mediaa; [2023]
    Keywords : Discontinuous Galerkin; Korteweg-de Vries; Conservation Laws; Partial Differential Equations; Numerical methods; Higher order spatial derivative; Heat Equation; Burgers’ Equation; Collocation; Lobatto Gauss Legendre; Stiffness; Nodal Approximation; Finite Volume; Finite Element;

    Abstract : In this thesis the Discontinuous Galerkin approximation performance applied to the Korteweg–de Vries equation is investigated. This equation is nonlinear with a third spatial derivative and can be used for shallow water movement. READ MORE
