  1. 1. Optimization of a Floor Grinding Machine for Uniform Grinding Pattern

    University essay from Linköpings universitet/Produktrealisering

    Author : Adithya Srikantha Dath; [2023]
    Keywords : Numerical Optimization; Floor Grinders; Grinding Pattern; Engineering Optimization; Model Based Systems; Data Analysis;

    Abstract : Husqvarna Construction is one of the leading construction machinery manufacturers in the world. To stay in the forefront, investing in novel methods to model, test & and optimize machinery is crucial. The most important part of development and testing is to bridge the gap between desired and actual results. READ MORE

  2. 2. On intermittency in the turbulent asymptotic suction boundary layer

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Edoardo Foschi; [2023]
    Keywords : Turbulence; turbulent boundary layer; intermittency; numerical simulation; DNS; tripping; suction;

    Abstract : This thesis presents a series of direct numerical simulations (DNS) performed in order to understand the discrepancy in the literature regarding turbulent asymptotic suction boundary layers (TASBLs) at low Reynolds numbers. The hypothesis to be tested is that the main reason for higher turbulence intensities observed in experiments compared to DNS is that the latter exhibits intermittent patches of laminar flow, developing both temporally and spatially.

  3. 3. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nipon Roy; [2023]
    Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

  4. 4. Thermal and flow field validation of lattice Boltzmann method solver

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : André Skagius-Kallin; [2023]
    Keywords : Lattice Boltzmann method; heat transfer; flow field;

    Abstract : Computational fluid dynamics, abbreviated CFD, is a valuable tool for several engineering applications. Applications such as heating, cooling or drying are some examples of areas where CFD is used. READ MORE

  5. 5. Numerical Simulations of Resonant Tunnelling Diodes

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Love Sundström; Alexander Holmström Janeld; [2023]
    Keywords : Quantum mechanics; numerical methods; resonant tunnelling diode;

    Abstract : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).
