1. 1. Evaluation of Physics Informed Neural Networks in engineering simple structural analysis problems

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Georgios Nentidis; [2023]
   Keywords : ;

   Abstract : Neural Networks have found many applications for a long time in Machine Learning in different disciplines, and have especially flourished in the last decade because of the ever-increasing processing power especially from GPUs. Because of their ability to operate as universal function approximators and model nonlinear processes, attempts have been made in recent years to be also used for modeling partial differential equation (PDE) solutions.

3. 2. 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

4. 3. CFD Analysis of the Flow Around a Paraglider Wing

   University essay from KTH/Teknisk mekanik

   Author : Caterina Gennari; [2023]
   Keywords : Paraglider Wing; CFD; RANS; DES; Aerodynamics; Aerodynamic Hysteresis; FSI; Deformable Structure; Membrane; Shell Elements;

   Abstract : In this study, the characteristics of the flow around a paraglider wing were investigated through the use of Computational Fluid Dynamics (CFD) simulations by solving both Reynolds Averaged Navier-Stokes equations and Delayed Detached Eddy Simulations were employed. This allowed the observation of how the unique shape of the canopy of a paraglider can influence the behaviour of the flow and how aerodynamic hysteresis can manifest on this sort of wing. READ MORE

5. 4. NVH analysis and optimization of electric powertrain

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Anujit Dafle; [2022]
   Keywords : Electric powertrain; Gear whine; Noise Vibration Harshness NVH ; Elektrisk drivlina; kuggvin; buller och vibrationer;

   Abstract : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. READ MORE

6. 5. Creation of a Finite Element Model andSystem Analysis for the Low and HighFrequency Cryogenic Telescopes of theSpace Mission LiteBIRD

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Matias Rittatore Texeira; [2022]
   Keywords : FEM; FEA; mesh model; CMB; IRAP;

   Abstract : The Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection (LiteBIRD) is a Japan Aerospace Exploration Agency (JAXA)-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the early Universe, through the measurement of their imprint onto the polarization of the Cosmic Microwave Background (CMB). It is an international collaboration, with European Union (EU) operations being coordinated by France. READ MORE
