  1. 1. 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

  3. 2. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis

    University essay from KTH/Betongbyggnad

    Author : Mohammad Mustafa Angar; [2020]
    Keywords : Pile cap; Nonlinear finite element analysis; ATENA 3D; Reinforcement layout; Strut and tie method; Pålfundament; icke-linjära finita elementmodeller; strut and tie-metoden;

    Abstract : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. READ MORE

  4. 3. Numerical Study on Seepage-induced Failure of Caisson Type Breakwaters Using a Stabilized ISPH

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Tetsuro Goda; [2017]
    Keywords : Tsunami; Breakwater; Particle method; SPH; Seepage flow; Technology and Engineering;

    Abstract : This paper presents a stabilized incompressible smoothed particle hydrodynamics (ISPH) method to simultaneously simulate surface and seepage flow. The Navier-Stokes type equation, which manipulates the linear and nonlinear resistance effects caused from porous materials, are employed for tracking fluid motions in porous medium. READ MORE

  5. 4. Design of Experimental Setup for Hydrodynamic Thin Film Pressure Study

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Muhammad Ishfaq Khan; [2012]
    Keywords : Hydrodynamic Thin Layer; 1-D Reynolds Equation; Unit-Step Geometry. ;

    Abstract : A proposed experimental setup for study and demonstration of the pressure distribution and load capacity of hydrodynamic bearings was developed. Various conceptual designs for producing thin full film lubrication conditions and enabling gap geometry control and pressure and force measurements were produced and assessed. READ MORE
