1. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskapSammanfattning : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

2. Introduction to the Hirota Direct Method
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : The primary subject matter of the report is the Hirota Direct Method, and the primary goal of the report is to describe and derive the method in detail, and then use it to produce analytic soliton solutions to the Boussinesq equation and the Korteweg-de Vries (KdV) equation. Our hope is that the report may also serve as an introduction to soliton theory at an undergraduate level. LÄS MER
3. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. LÄS MER
4. Numerical solutions to the Boussinesq equation and the Korteweg-de Vries equation
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : The aim of the report is to numerically construct solutions to two analytically solvable non-linear differential equations: the Korteweg–De Vries equation and the Boussinesq equation. To accomplish this, a range of numerical methods where implemented, including Galerkin methods. LÄS MER
5. Strain Accumulation Due to Cyclic Loadings
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : The formation of plastic strains in non-cohesive soils due to large number of loading cycles is a phenomenon of great importance in geotechnical and civil engineering. It constitutes a considerable cause for failures and deformations in various types of engineering applications including pavements. LÄS MER
