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. Lid driven cavity flow using stencil-based numerical methods
Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : In this report the regular finite differences method (FDM) and a least-squares radial basis function-generated finite differences method (RBF-FD-LS) is used to solve the two-dimensional incompressible Navier-Stokes equations for the lid driven cavity problem. The Navier-Stokes equations is solved using stream function-vorticity formulation. 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. Finite Element Approximations of 2D Incompressible Navier-Stokes Equations Using Residual Viscosity
Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaperSammanfattning : Chorin’s method, Incremental Pressure Correction Scheme (IPCS) and Crank-Nicolson’s method (CN) are three numerical methods that were investigated in this study. These methods were here used for solving the incompressible Navier-Stokes equations, which describe the motion of an incompressible fluid, in three different benchmark problems. LÄS MER
5. Energipålar - Termiskt responstest på prefabricerad energipåle i betong
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)Sammanfattning : Energipålar är grundläggningspålar kombinerade med kollektorslangar som används som vertikala markvärmeväxlare. De har sedan 1980-talet använts i Centraleuropa, och används även frekvent i England. I Sverige har energipålar ännu inte slagit igenom, men de större byggföretagen börjar nu intressera sig för denna typ av grundläggning. LÄS MER
