  1. 6. 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

    University essay from KTH/Farkostteknik och Solidmekanik; KTH/Kraft- och värmeteknologi

    Author : Hector Älfvåg; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 7. Design of a High Subsonic Nozzle for a Transonic Linear Cascade Operating at Near Stall Conditions

    University essay from KTH/Energiteknik

    Author : César Lucio; [2021]
    Keywords : ;

    Abstract : This thesis presents the results of computational fluid dynamics (CFD) design calculations of a subsonic nozzle operating at Mach number 0.85 in a transonic linear cascade wind tunnel. The purpose of the nozzle is to accelerate a fluid by decreasing the pressure energy and raising the kinetic one. READ MORE

  4. 8. Dimples in corrugated channels to improve efficiency in plate heat exchangers

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gustav Karlsson; [2020]

    Abstract : The development of new heat exchanger patterns is ever changing. Companies are constantly pushing innovation to satisfy costumer needs in terms of thermal efficiency, reliability and serviceability. In this thesis, the implementation of dimples in the corrugated pattern of a plate heat exchanger is investigated to increase the thermal efficiency. READ MORE

  5. 9. Influence of Reynolds Number and Heat Flux when Cooling an Array of Cylinders

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Erik Fagerström; [2020]
    Keywords : Reynolds Number; Heat Flux; Porous Media; Cooling;

    Abstract : When batteries are used, it is of interest to know how high the temperature will become and if the cooling is efficient enough. In this thesis project, the geometry used are batteries placed in an array shape, inside a box. This gives the possibility of assuming porosity conditions when looking at the box from the outside.

  6. 10. Numerical Investigation of Various Modelling Strategies for Throttling a Transonic Compressor Rig Diffuser

    University essay from KTH/Kraft- och värmeteknologi

    Author : Borzou Dargahi; [2019]
    Keywords : ;

    Abstract : The concern of this study is modeling of the flow field in the diffuser of a 1.5 stage compressor test rig in which the mass flow is constrained at the exit of the diffuser. Constraining method is is applied through, throttling by means of a slab at the exit of the diffuser, where the flow enters the exit volute. READ MORE
