  1. 1. Forced response numerical investigation of a transonic compressor rotor

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

    Author : Mariana Pires Gonçalves Toco Dias; [2023]
    Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

  3. 2. Automatic analysis of tool status in band saws

    University essay from Umeå universitet/Institutionen för fysik

    Author : Axel Östman; [2022]
    Keywords : ;

    Abstract : The products with the highest return and longest life cycle in the sawmill industry are boards and planks. Unfortunately, a large part of the log becomes bi-products during the cutting process. One way to reduce the amount of bi-products in a sawline is to saw with as thin kerfs as possible. That is the cut of the blade. READ MORE

  4. 3. Development and study of noise generation from propellers

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Anton Anton Dunström; Fredrik Skjernov; [2022]
    Keywords : Silent propellers; Propeller development; Noise generation; Skew angle; Blade Area Ratio; Openprop; NATO STANAG no. 1136; Swedish defense and Research Agency FOI ; James Fisher Defense.; Tysta propellrar; Propellerutveckling; Ljudskapande; Skevningsvinkel; Bladtäckningsarea; Openprop; NATO STANAG no. 1136; FOI; James Fisher Defense.;

    Abstract : Noise generation from underwater activities propagates into the marine environment.For marine vessels the propulsion system generates the most noise during itsoperations. Naval vessels that want to operate without being detected want to controlthe sound generating properties of the vessel. READ MORE

  5. 4. Design of a radial-inflow microturbine for combined heat and power generation unit

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Salvador María Beltrán Martínez; [2021]
    Keywords : radial inflow turbine; turbomachinery; rotor; nozzle vanes; reaction; design; TurbAero; CAD; blade speed ratio; specific speed; efficiency; turbine exhaust; turbine; inlet; pressure drop; Euler equation; losses; blade loading plot; pressure side; suction side; Technology and Engineering;

    Abstract : This project aims to design a radial inflow microturbine that will be part of a system to generate both heat and electricity. Considering the specific power and the mass flow rates involved with the system, a radial inflow turbine was chosen. This type of turbine provides much larger power density in a single stage compared to the other types.. READ MORE

  6. 5. 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
