  1. 6. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

    University essay from Uppsala universitet/Signaler och system

    Author : Simon Wredh; [2020]
    Keywords : computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

    Abstract : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. READ MORE

  3. 7. Two-dimensional Study of Blade Profiles for a Savonius Wind Turbine

    University essay from Uppsala universitet/Elektricitetslära

    Author : Johanna Sundberg; Martina Lundberg; Julia Solhed; Aikaterini Manousidou; [2020]
    Keywords : Savonius rotor; vertical axis wind turbines; Ansys Fluent; k-omega SST; overlap ratio; blade arc angle;

    Abstract : A Savonius wind turbine is a self-starting vertical axis rotor. It can be designed to be compact in size and also produces less noise which makes it suitable to integrate into urban spaces such as rooftops and sign-poles. READ MORE

  4. 8. 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).

  5. 9. LES Modelling of Turbulent Flow Through an Array of Cylinders Using OpenFOAM

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Hanna Isaksson; [2019]
    Keywords : Porous media; OpenFOAM; premeability; LES; packed cylinders; turbulence;

    Abstract : The objective for this master thesis project was to perform simulations for high and low Reynolds number for a porousmedia modelled as quadratic packed cylinders. The simulations were to be performed by using the open source codeOpenFOAM and the turbulence should be modelled by the LES turbulence model in order to resolve details about theturbulence.

  6. 10. Modelling coaxial jets relevat to turbofan jet engines

    University essay from KTH/Mekanik

    Author : Asuka Gabrielle Pietroniro; [2016]
    Keywords : ;

    Abstract : Simulations of subsonic turbulent coaxial hot jets were conducted on two types ofunstructured grids within the framework of STAR-CCM+. The study case is based on atypical airliner turbofan engine model with a core nozzle and a fan nozzle, having a bypassratio of five. READ MORE
