1. 1. Fluid/Material Coupled Numerical Analysis of Single Bubble Collapse Near a Pit on a Wall

   Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

   Författare :Daiki Makii; [2020]
   Nyckelord :Bubble Dynamics; Cavitation Erosion; Numerical Analysis; Fluid Material Coupled Numerical Method; Homogeneous Model; Elastic Body Material; Erosion Pit;

   Sammanfattning : In order to elucidate the progression mechanism of cavitation erosion, the behaviors of a single cavitation bubble collapse near a pit on a wall and both the resulting pressure wave in fluid and stress wave in material are investigated in detail. To find out the mechanism of cavitation erosion, many experimental studies on the bubble collapse behavior near a flat rigid wall and the resulting material damage have been conducted so far.

3. 2. A CFD Method for Simulation of Gas-Liquid Flow in Cooling Systems : An Eulerian-Eulerian Approach

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Malin Lind; Karl Johan Josefsson; [2016]
   Nyckelord :CFD; Gas-Liquid; Two-phase; Eulerian; Air bubbles; Flow; Eulerian-Eulerian; Cooling system;

   Sammanfattning : When designing modern engines it is important to construct a cooling system that cools the engine structure efficiently. Within the cooling system there is always a certain amount of air which can accumulate and form air pockets in critical areas, such as the water jacket, which can lead to wall degradation. LÄS MER
