  1. 1. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kaibin Wen; [2023]
    Keywords : Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

    Abstract : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. READ MORE

  3. 2. CFD validation of a new gas turbinestage design with experimental data

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Claudia Florentina Balan; [2022]
    Keywords : ;

    Abstract : Gas turbines are present in two energy-intensive sectors: aviation and energy production. Improving the efficiency of gas turbines has a huge impact on the reduction of CO2 in the atmosphere, therefore many research groups are studying innovative strategies to improve the performance of these turbines.

  4. 3. 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

  5. 4. Duct mode evaluation for traction motor outlets

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Michail Vourakis; [2020]
    Keywords : ;

    Abstract : This study investigates duct mode propagation at outlets of traction motors, featuring an open fan air-cooled architecture. Both acoustical measurements and simulations are employed. Measurements are performed for two duct outlet geometries, a radial and a non-radial outlet, both combined with an equidistant and a non-equidistant blade fan. READ MORE

  6. 5. Development of a Profile Sample Cutter

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Maryam Tarik Hamad; [2020]
    Keywords : Blade geometry; vertical constraint; paper properties; paper slitting; Knivbladsgeometri; vertikal begränsning; pappersegenskaper; pappersskärning;

    Abstract : The pulp- and paper industry is a key industry globally and stands for a production of 600 million tonnes pulp and paper worldwide with a total revenue of 400 billion dollars. Due to high quality requirements on paper, it is important to use instruments that control that the produced paper fulfill the promised requirements. READ MORE
