Analysis of software solutions for particle motion in moving fluids
Bohuslav, Marek ; Vacula, Jiří (referee) ; Novotný, Pavel (advisor)
The issue of particle motion in moving fluids is a more frequently discussed topic in the automotive industry concerning the new EURO 7 emission standards. Requirements include particles from brakes, tire wear and exhaust gases and their limitations. To limit them, it is possible to capture them and for that, the behaviour of the particles needs to be predicted. Particle behaviour can be simulated using the right software, which requires an understanding of flow physics to be set up. The bachelor's thesis offers a complete overview of the CFD principles of flow and particle motion in fluids. In the second part, the thesis provides an overview and analysis of usable software for particle flow solutions with examples of their practical use in this matter. The third part focuses on the demonstration of particle flow in the numerical simulation in the software Ansys CFX, particularly in a simulation of particle motion in oil in a slide bearing. The demonstration includes an analysis of the results and provides useful insights and tips for creating a simulation in Ansys CFX.
