  1. 11. Methods of post-treatment of aerodynamic tests of engine boosters

    University essay from KTH/Kraft- och värmeteknologi

    Author : Jacques Jazzar; [2019]
    Keywords : Low pressure compressor; Post-testing methodology; Compressor map; Performances analysis; Tool development; Lågtryckskompressor; Efterprövningsmetodik; Kompressorkarta; Prestandasanalys; Verktygsutveckling;

    Abstract : Aerodynamics studies in a booster such as analysis of the flow through the whole component or study of local turbulent phenomenon constitute a crucial part of its development in order to get better overall performances, like efficiency of the compressor and compression ratio. In order to put in perspective the computational predictions, it is critical to obtain sets of data from tests to caliber numerical analyses and to assure the booster respects design specifications.

  3. 12. Experimental assessment of fluid hammer prediction algorithms

    University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Author : Jessica Kihlström; [2018]
    Keywords : ;

    Abstract : Fluid hammer is a problem, which may lead to catastrophic consequences and many engineers have a deficiency in competence when it comes to its prediction. This study´s objective is to assess various fluid hammer prediction models, to evaluate how substantial pressure thrusts would affect a system and to verify the analytical results toward experimental data.

  4. 13. Dynamic Soil-Structure Interaction of a Portal Frame Railway Bridge - Numerical Analysis on a Case Study Bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Rita Ikzer; [2018]
    Keywords : Dynamic Analysis; Soil-Structure Interaction; Damping; Railway Bridge; Portal Frame Bridge; Full FE-Modeling; Simplified Modeling; Dynamisk analys; Jord-struktur interaktion; Dämpning; Järnvägsbro; Plattrambro; Detaljerad FE-modellering; Förenklad modellering;

    Abstract : In the field of structural dynamics, a broader knowledge about relevant phenomena that affect the dynamic behavior of railway bridges is vital for structural engineers and design code administrators. The knowledge might benefit in an increased understanding of e.g. the resonance phenomena, and in improvements of the existing design codes. READ MORE

  5. 14. Numerical Analysis of Latent Thermal EnergyStorage in Coaxial Component

    University essay from KTH/Energiteknik

    Author : Hampus Nilsson; [2017]
    Keywords : ;

    Abstract : Latent Thermal Energy Storage, LTES, is a system for storing energy for later use. It isused in applications such as buildings, electronics and space shuttles. The problem associatedwith the system is the relatively low charging and discharging power i.e. READ MORE

  6. 15. Wind Power Forecast Accuracy in Scandinavia:Analysis of Forecast Errors Using TAPM

    University essay from KTH/Kraft- och värmeteknologi

    Author : Sara Jarmander; [2017]
    Keywords : ;

    Abstract : Wind power has different characteristics compared to conventional energy sources. The main difference is that wind power fluctuates under the influence of meteorological variables. This gives rise to problems related to grid stability. READ MORE
