1. 1. Design Investigation into Liquid Oxygen Vaporisation Systems : Atomisation and Heat Loads

   University essay from KTH/Energiteknik

   Author : Borbala Bernus; [2020]
   Keywords : LOx; gasification; two-phase CFD simulation; rapid oxidation; rocket; cryogenic; hybrid; atomisation; LOx; förgasning; 2-fas CFD-simulering; snabb oxidation; raket; kryogen; hybrid; atomisering;

   Abstract : Computational Fluid Dynamics (CFD) simulations are presented within this study for super-cooled liquid oxygen atomisation and gasification in a subcritical chamber operating at 1MPa. Relatively low cost simulation techniques have been used and their accuracy evaluated. READ MORE

3. 2. Numerical Analysis ofLatent Thermal Energy Storage in a Cavity

   University essay from KTH/Energiteknik

   Author : Robert Olrog; [2017]
   Keywords : ;

   Abstract : Latent Thermal Energy Storage (LTES) has drawn attention because the technology is a simple and cost-efficient method to store large amounts of energy. Latent energy is either stored or released when the material inside the LTES undergoes phase-change. READ MORE

4. 3. Influence of In-vessel Pressure and Corium Melt Properties on Global Vessel Wall Failure of Nordic-type BWRs

   University essay from KTH/Kärnkraftssäkerhet

   Author : Andrei Goronovski; [2013]
   Keywords : Severe accident; Vessel failure; CRGT cooling; Thermo-Mechanical creep analysis;

   Abstract : The goal of the present study is to investigate the effect of different scenarios of core degradation in a Nordic-type BWR (boiling water reactor) on the reactor pressure vessel failure mode and timing. Specifically we consider the effects of (i) in-vessel pressure, (ii) melt properties. READ MORE

5. 4. Ag-In transient liquid phase bonding for high temperature stainless steel micro actuators

   University essay from Mikrosystemteknik

   Author : Martin Andersson; [2013]
   Keywords : TLP; PCM; microactuator; mannitol; high temperature; microsystems;

   Abstract : A stainless steel, high temperature, phase change micro actuator has been demonstrated using the solid-liquid phase transition of mannitol at 168°C and In-Ag transient liquid phase diffusion bonding. Joints created with this bonding technique can sustain temperatures up to 695°C, while being bonded at only 180°C, and have thicknesses between 1. READ MORE

6. 5. CFD modeling of heat charging process in a direct-contact container for mobilized thermal energy storage

   University essay from

   Author : Arefeh Hesaraki; [2011]
   Keywords : ;

   Abstract : Thermal energy storage and phase change materials become increasingly important topics during the last 20 years for heating and cooling purpose in buildings. When there is time delay or mismatch between producing energy and energy demand, thermal energy storage provides a great solution. READ MORE
