1. 1. Large Eddy Simulation of Cavitating Flow on Hydrofoils

   Författare :Nai Xian Lu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Cavitation is the occurrence of vapour pockets in liquids due to the phenomenon that liquid may turn into vapour when the pressure in the flow is lowered below the vaporization pressure. It often brings negative effects such as performance degradation, noise and vibration, and material damage, therefore becoming one of the limiting factors when designing the propulsion systems.

3. 2. Modelling Cavitation Mechanisms Using Large Eddy Simulation

   Författare :Nai Xian Lu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrodynamics; Cavitation; cavitation erosion; cavitation mechanisms; numerical simulation; LES;

   Sammanfattning : Cavitation often brings negative effects such as performance degradation, noise and vibration, and material damage, being one of the limiting factors when designing propulsion systems. On the other hand, cavitation must be endured for an efficiently propelled system. LÄS MER
