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. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. LÄS MER
3. The Potential Use of Degradable Starch Microspheres as a Carrier for Nasal Drug Administration
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : Intranasal drug delivery is a practical and accessible method for treating localized symptoms as well as achieving systemic drug absorption. The approach takes advantage of the permeability, vascularization, and limited enzymatic activity of nasal tissue, leading to enhanced drug absorption. LÄS MER
4. 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
5. Salivary flow rate and xerostomia in patients with head and neck cancer after radiation therapy
Master-uppsats, Umeå universitet/TandläkarutbildningSammanfattning : Background: Radiation therapy used for head and neck cancer patients cause many side effects in the oral cavity and above all affects the salivary glands. Complaint of dry mouth (xerostomia) and hyposalivation are common as well as swallowing difficulty (dysphagia) even after the cancer is remitted. LÄS MER
