Sammanfattning : We present an overlapping mesh based splitting method for solving the incompressible Navier-Stokes equations on unfitted mesh settings. The developed method is based on Nitsche’s method for weakly imposing the interface condition between the overlapping meshes, and it uses a ghost penalty approach for stabilizing the cut elements produced by the mesh intersection.

Sammanfattning : In a paper from 1970, Lortz constructs rotational solutions to the steady Euler equation in toroidal domains using a fixed point method. We shall review this method and rewrite it using Banach's fixed point theorem. LÄS MER
3. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF modelUppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära
Sammanfattning : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. LÄS MER

Sammanfattning : Colorless distributed combustion (CDC) is a promising novel technology to reduce emissions of carbon monoxide and nitrogen oxides in gas turbine combustors. CDC features a different flame regime than conventional gas turbine combustors, associated with a distributed reaction zone and low and uniform temperatures due to dilution of combustion air with exhaust gases.

Sammanfattning : A common approach in numerical studies of elastohydrodynamic lubrication (EHL) is based on solving the Reynolds equation that governs pressure distribution in thin lubricant films. The Reynolds equation is derived from the Navier-Stokes equations by taking assumptions that are considered valid when the thickness of the lubricant film is much smaller than its length. LÄS MER
