  1. 1. Stochastic Optimal Trajectory Generation via Multivariate Polynomial Chaos

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

    Author : Lisa Whittle; [2017]
    Keywords : ;

    Abstract : This thesis presents a framework that has been developed in order to compute stochastic optimal trajectories. This is achieved by transforming the initial set of stochastic ordinary differential equations into their deterministic equivalent by application of Multivariate Polynomial Chaos. READ MORE

  2. 2. Tip vortex cavitation and diffused vorticity of propeller profiles: a modelling approach : Investigation of an implemented TVI model, and  implementation and investigation of a DVH model

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Lukas Lundin; [2017]
    Keywords : Vortex dynamics; Cavitation; TVI; DVH; Von Kármán Vortex Street; Virveldynamik; Cavitering; TVI; DVH; Von Kármán virvelgata;

    Abstract : To predict fluid properties and interactions is an important task for the industry. It is plagued, however, by being close to impossible to predict analytically. Hence, it is customary to turn to numerical solutions. This in itself comes with many different methods and approaches suitable for different needs. READ MORE

  3. 3. Development of a Test Suite for Verification & Validation of OpenFOAM

    University essay from Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Author : Simon Persson; [2017]
    Keywords : Verification; Validation; OpenFOAM; CFD; MMS; Manufactured Solution;

    Abstract : Computational fluid dynamics is an important tool which can be used to simulatevarious properties of a flow. CFD simulations are used within the nuclear powerindustry to aid in the evaluation of thermal loads within a given system. In order toverify and validate some aspects of the open source solver OpenFOAM a test suitewas developed. READ MORE

  4. 4. Silicon solar cells: basics of simulation and modelling : Using the mathematical program Maple to simulate and model a silicon solar cell

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Sebastian Ekhagen; [2017]
    Keywords : solar cell; semiconductor; physics; condensed matter physics; solid state physics; applied physics; solcell; halvledare; fysik; material fysik; applicerad fysik; fasta tillståndets fysik.;

    Abstract : The main goal of this thesis was to simulate a solar cell with the symbolic manipulation tool Maple and discuss the strength and weaknesses of using Maple instead of the already known simulation program PC1D. This was done mainly by solving the three essential differential equations governing the current density and excess electron and hole densities in the solar cell. READ MORE

  5. 5. Nonradial Solutions of a Nonlinear Elliptic Equation

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Sebastian Andersson; [2017]
    Keywords : Mathematics and Statistics;

    Abstract : We consider the partial differential equation ∆u + f(u) = 0 in two dimensions,where f is a nonlinear function of u. Under certain assumptions on f we show that the equation has non-radial C² solutions with u(x) → 0 as |x| → 0 with an arbitrary number of zeros on each axis. READ MORE
