  1. 1. Development of a Method to Determine the Influence of Rubber Components in Dynamic Simulations

    Master-uppsats, KTH/Farkostteknik och Solidmekanik

    Författare :Mårten Vuorinen; [2022]
    Nyckelord :;

    Sammanfattning : In order to make sure that an engine can withstand the vibration loads, while the weight is kept as low as possible, some components on the engine are made of rubber. The stiffness of these rubber components are several orders of magnitude lower than the surrounding metal components, and the inclusion of rubber components affects the dynamic behaviour of the engine.

    Sammanfattning : Hydrofoiling in general has the potential to revolutionize watercraft in the future since it allows smoother and faster transport on water with less energy consumption than traditional planning hulls. Even if the concept of hydrofoiling has been around since the last century, development in control theory and material science together with increased computing power has led to a growing interest for the technology.

  4. 3. Parametric Study of Separation in Outlet Diffuser of Rocket Nozzle Cooling Channel Rig : The Effect of Heat Flux and Angle of Outlet Diffuser for Rectangular-to-Circular Cross Section Transitions

    Master-uppsats, KTH/Farkostteknik och Solidmekanik; KTH/Kraft- och värmeteknologi

    Författare :Hector Älfvåg; [2021]
    Nyckelord :;

    Sammanfattning : The use of natural gas with high methane content as rocket fuel has gained substantial industrial attention over the past number of years. Several actors including SpaceX and Blue Origin are developing natural gas powered rocket engines. LÄS MER

  5. 4. Design and Calibration of Pneumatic Probes for Aerodynamic Testing

    Master-uppsats, KTH/Farkostteknik och Solidmekanik; KTH/Kraft- och värmeteknologi

    Författare :Angelica Lejdeby; [2021]
    Nyckelord :;

    Sammanfattning : To develop turbomachines aerodynamic testing is an important part of the process. The performance testing this thesis will focus on is pressure measurements, which often is done using pneumatic probes. The pneumatic probes used in this project were a five-hole probe, a pitot probe and two different types of Kiel probes. LÄS MER

  7. 5. Influence of Climate Change on Building Effluent Wastewater Temperature in Stockholm by 2040

    Master-uppsats, KTH/Energiteknik; KTH/Farkostteknik och Solidmekanik

    Författare :Sorhenn Gourhand Martin; [2021]
    Nyckelord :;

    Sammanfattning : This report aims to give predictions of Stockholm’s region climate (especially temperature and precipitations) by 2040 and describe the consequences of possible climate changes on the building effluent water temperature and flowrate. First, I did an extensive review of the literature about climate change and climate prediction in Stockholm’s area in order to suggest probable climate scenarios for 2040, using climatic data from the reference period 1960-1990.
