   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :André Skagius-Kallin; [2023]
   Nyckelord :Lattice Boltzmann method; heat transfer; flow field;

   Sammanfattning : Computational fluid dynamics, abbreviated CFD, is a valuable tool for several engineering applications. Applications such as heating, cooling or drying are some examples of areas where CFD is used. LÄS MER

3. 2. Model of Thermal EHL Based on Navier-Stokes Equations : Effects of Asperities and Extreme Loads

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Marko Tošić; [2019]
   Nyckelord :;

   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

4. 3. Numerical simulations of mixing for gas exhaust treatment

   Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

   Författare :Viktor Lahti; [2019]
   Nyckelord :;

   Sammanfattning : According to the World Health Organisation, nine out of ten people live in places with sub par air quality. Therefore, the study of the treatment of polluted air is from a global point of view of great importance, and a matter of life quality for both humans and as well as animals. LÄS MER

5. 4. CFD Modeling and Optimization of Primary sedimentation tank

   Master-uppsats, KTH/Vattendragsteknik

   Författare :Aibin Zhang; [2017]
   Nyckelord :VOF model; RNG k-ε model; velocity; turbulence; primary sedimentation tank;

   Sammanfattning : In this project, the flow field characteristics of the simplified 2D rectangular primary sedimentation tank in Syvab wastewater treatment plant were achieved by a transient water-air two phases finite-volume method, applying Volume-Of-Fluid (VOF) model. RNG k-ε turbulence model was also employed to calculate the turbulent kinetic energy and its dissipation rate. LÄS MER

7. 5. CFD Simulation of Jet Cooling andImplementation of Flow Solvers inGPU

   Master-uppsats, KTH/Numerisk analys, NA

   Författare :Md. Lokman Hosain; [2013]
   Nyckelord :;

   Sammanfattning : In rolling of steel into thin sheets the final step is the cooling of the finished product on the Runout Table. In this thesis, the heat transfer into a water jet impinging on a hot flat steel plate was studied as the key cooling process on the runout table. The temperature of the plate was kept under the boiling point. LÄS MER
