  1. 21. Neural Network-based Optimization of Solid- and Fluid Mechanical Simulations

    University essay from KTH/Matematik (Avd.)

    Author : Pablo Jeken Rico; [2021]
    Keywords : PU Foaming Simulations; Computer Vision; Artificial Neural Networks; Polyuretanskumning Simuleringar; Computer Vision; Artificiella Neurala Nätverk;

    Abstract : The following project deals with the optimization of simulation parameters such as the injection location and pitch angle of polyurethane foaming simulations using artificial neural networks. The model's target is to predict quality variables based on the process parameters and the geometry features. READ MORE

  3. 22. Active Control of High­-Speed Flexible Rotors on Controllable Tilting­-Pad Journal Bearings : Theory and Experiment

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Paul-Henrik Bull; [2021]
    Keywords : ATPJB; Fluid-Film Lubrication; Model based control; Vibration Control;

    Abstract : A common choice of bearing for industrial applications such as turbomachinery and rotating compressors is the Tilting-Pad Journal Bearing (TPJB) due to its excellent stability properties. TPJB's are however limited by the reduction of damping in the fluid film at high velocities. READ MORE

  4. 23. Analytical Exponential-6 Equation of State Based on Monte Carlo Simulations

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Peter Hallstadius; [2021]
    Keywords : Equation of state; exp-6; Monte Carlo; detonation; shock wave; thermochemical code; Technology and Engineering;

    Abstract : The exponential-6 (exp-6) potential is an intermolecular pair potential that is widely used to model fluids at high densities. The path from molecular interaction to equation of state (EOS) for a gas is not straightforward however. READ MORE

  5. 24. Development of patient-specific fetal head phantom for experimental evaluation of vacuum assisted delivery

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Maria Pop; [2021]
    Keywords : Vacuum assisted delivery; Vacuum extractor device; Traction force; Vacuum pressure; Fetal head phantom; Ultrasound imaging; Sonomicrometry;

    Abstract : Vacuum assisted delivery (VAD) is a common procedure used in the final stage of labor in the situation of a difficult natural delivery. Since the only biomechanical studies concerning the clinical safe traction force were conducted during 70s using simplified models to mimic the fetal head, concerns remain regarding the side effects of this medical intervention when applying high levels of traction forces.

  6. 25. External Heat Transfer Coefficient Predictions on a Transonic Turbine Nozzle Guide Vane Using Computational Fluid Dynamics

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Daniel Enico; [2021]
    Keywords : CFD; LS89; transonic turbine; transition; transition model; turbulence decay; turbulence intensity; length scale; turbulence characteristics; HTC; external heat transfer coefficient; Steelant-Dick postulation;

    Abstract : The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. READ MORE
