  1. 6. Experimental and CFD Study of Heat Pickup in Cooling System Hoses

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : August Borg; Michael Owen; [2019]
    Keywords : ;

    Abstract : This thesis investigates a process known as heat pickup which occurs in vehicle cooling system hoses. Heat pickup is an unwanted side effect of temperature differences in a car underhood compartment, whereby excess heat is tranferred into the coolant running through the cooling system hoses, affecting its operating temperature.

  3. 7. Enabling high-fidelity measurements of turbulent boundary layer flow over wing sections in the MTL wind tunnel.

    University essay from KTH/Mekanik

    Author : Fermin Mallor; [2019]
    Keywords : Fluid mechanics; aerodynamics; turbulence; RANS; wind-tunnel experiments; insert design; Strömningsmekanik; aerodynamik; turbulens; RANS; vindtunnel experiment; inlaga designen;

    Abstract : A reinforced fiber-glass model of a NACA 4412 wing profile is designed and set-up in the Minimum Turbulence Level (MTL) wind tunnel facility at KTH. The model has 65 pressure taps orifices, and the set-up includes two mounting panels designed to allow for particle image velocimetry (PIV) and hot wire anemometry (HWA) measurements of the boundary layer (to be performed in a future campaign).

  4. 8. Robust optimisation of the pressure-gradient distribution in turbulent boundary layers

    University essay from KTH/Mekanik

    Author : Yuki Morita; [2019]
    Keywords : ;

    Abstract : In order to better characterise pressure-gradient turbulent boundary layers (TBLs), and to advance the theory of these flows, typically canonical conditions are required. This is achieved by keeping the Clauser pressure-gradient parameter, β, constant along the streamwise direction, see for instance Mellor and Gibson [9] and Bobke et al. READ MORE

  5. 9. Numerical simulation and experimental validation of a manufactured wing profile

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Niklas Olsson; Christian Selberg; [2019]
    Keywords : Flow; surface roughness; airfoil;

    Abstract : The background for this thesis originates from a study of the flow characteristics for an airfoil of the type NACA0018. The aim for this thesis was to evaluate how the characteristics of the flow over the NACA0018 profile depend on surface roughness. READ MORE

  6. 10. An experimental study of surface coatings to limit the impact of frosting

    University essay from KTH/Energiteknik

    Author : Carl Andersson; [2018]
    Keywords : ;

    Abstract : Heat pumps are commonly used as a way to efficiently meet heating demands. The efficiency and flexibility of Air-source heat pumps (ASHPs) have improved in recent years and is an attractive heating solution suitable for houses with lower heating demands, as it is inexpensive to purchase and install compared to other heating solutions.
