  1. 1. Aerodynamic Optimization of Low Observable Engine Intake Duct

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

    Author : Laszlo Vimlati; [2022]
    Keywords : NSGA-II; CFD; Air Intake; S-Duct; Optimization; Pressure Recovery; Distortion.; NSGA-II; CFD; Intagskanal; Optimering; Tryckåtervinst; Flödesdistorsion.;

    Abstract : An aerodynamic shape optimization procedure was performed on a low observable engineintake duct. The intake duct was fixed in its throat and aerodynamic interface plane (AIP)sections, while leaving up to 7 design parameters free to deformation in the centroid curveand mid section profile.

  3. 2. Shape optimization of axial cooling fan via 3D CFD simulation and surrogate modeling

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Martin Granlöf; [2021]
    Keywords : Fan noise; shape optimization; mesh morphing; computational fluid dynamics; computational aeroacoustics; Efficient Global Optimization; Reynolds-averaged Navier-Stokes;

    Abstract : Due to legislative reasons and environmental concerns the automotive and transport sector are shifting their focus from traditional internal combustion engine (ICE) vehicles to development of battery electric vehicles (BEVs). This brings new challanges to design of cooling systems where axial fans are one of the key components. READ MORE

  4. 3. Towards a method for antenna impedance tailoring through shapeoptimization, with a bound on the associated cost-function

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Cem Kesici; [2020]
    Keywords : ;

    Abstract : Over the last years, there has been an interest in designing antennas that operateat higher frequencies. In most applications, these antennas work jointly withPower Amplifiers. However, most commercial Power Amplifiers have a nonstandardoptimal load-pull impedance in their optimal operating frequencies. READ MORE

  5. 4. Design analysis and optimization of the Hyperloop shell and chassis

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

    Author : Fangzhou Shao; [2019]
    Keywords : FE analysis; shape optimization; topology optimization; Optistruct; composite material; FE-analys; formoptimering; optimering av topologi; optistrukt; kompositmaterial;

    Abstract : In the past decades of years, huge amounts of people chose to move to big cities for better education and medical service, which also makes many cities are very crowded and noisy. Moreover, the house rent in city center is some kind too expensive for many people, especially for the youth. READ MORE
