    Abstract : Accurately modeling aerodynamic forces and moments are crucial for understanding thebehavior of an aircraft when performing various maneuvers at different flight conditions.However, this task is challenging due to complex nonlinear dependencies on manydifferent parameters. READ MORE

  3. 2. A Numerical Approach for Wind Tunnel Noise Control

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Hampus Dall; Robert Palm; [2021]
    Keywords : Technical Acoustics; ANC; Active Noise Control; Superposition; Wind Tunnel; Wingsuit; Indoor Wingsuit; Higher Order Modal Acoustic Field Beyond Plane Wave Region; Numerical Acoustic Simulations; Teknisk Akustik; Aktiv Brusreducering; Superposition; Vindtunnel; Flygning med ekorrdräkt inomhus; Högre ordningens akustisk modanalys bortom planvågsteori; Numeriska akustiska simuleringar;

    Abstract : A wind tunnel from the 1950s located in Bromma, Stockholm, once used for military research is today used for commercial activities. Today the tunnel is used for indoor wingsuit flight and the facility has an interest in reducing the overall noise generated by the tunnel. Acoustic measurements indicate noise problems in the 50 Hz range. READ MORE

  4. 3. Production Process for Tunnel Modeling : An Analysis of Composites for Water Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Melody Ghaderidosst; Vilma Hurtigh Grabe; Rebecka Norman; Adam Rosvall; Evelina Wiksten; [2021]
    Keywords : Tunnel Modeling; Water Applications; Composites; Natural Fibers; Polymers;

    Abstract : Hydroelectric power is a leading source of renewable energy where large turbines convert the kinetic energy of water into electricity. In order to not exceed the capacity limit of the turbine, excess water in the dams needs to be diverted away through spillways. READ MORE

  5. 4. Predicting the Performance of a Cleaning Nozzle : A Cost-Effective CFD Modeling Approach Compared Against Experimental Data

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Gustav Rydholm; Joseph Hainsworth; [2021]
    Keywords : CFD; VOF; LPT; EWF;

    Abstract : With the increasing reliance and use of sensors to improve the capabilities of modern road vehicles, ensuring their functionality during different weather conditions has become an important design consideration. The sensing equipment is utilized for a multitude of tasks, ranging from aiding the user with parking to avoiding potentially dangerous situations. READ MORE

  6. 5. Modeling contingency infiltration scenarios in MODFLOW : Stockholm Bypass and tunnel induced groundwater drawdown

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Aslan Abdo; [2019]
    Keywords : tunnel induced groundwater drawdown; MODFLOW; artificial recharge; land subsidence; grundvattenavsänkning; tunnel inläckage; MODFLOW; infiltration; sättning;

    Abstract : Subsurface constructions, such as tunnels, create hydrogeological challenges in mitigating risk of subsidence due to groundwater drawdown. Presenting readily made precautionary mitigation plans, such as strategically planned artificial recharge applications, can help effectivise the mitigation process. READ MORE
