Description
Description
Cavitation is a phenomenon in which the static pressure of a liquid drops below the vapor pressure of the liquid, leading to the formation of small voids filled with vapor in the liquid.
When these cavities are subjected to higher pressures, they collapse and can create shock waves that may damage machinery. These shock waves are strong when close to the bursting bubble, but weaken rapidly as they propagate away from the burst.
Cavitation is an important cause of wear in some engineering fields. Collapsing cavities that explode near the metal surface cause cyclic stress through repeated bursting. This leads to fatigue of the metal surface, which causes a type of wear also called “cavitation”.
The geometry of the present project is designed in Design modeler and meshed in ANSYS Meshing software. The mesh type is unstructured and the element number is equal to 2,446,879.
Boat Propeller Cavitation Methodology
The Mixture multiphase model was used in this project to simulate the cavitation occurring in the vicinity of propeller’s blades. Cavitation occurs due to the pressure drop on one side of the blades. Schnerr-Sauer model has been enabled to simulate the cavitation and vaporization pressure limit was set to 3540 Pa.
Furthermore, SST k-omega model is used to solve for the turbulent fluid equations. This model provides higher accuracies when simulating external flows. The mesh motion option was also enabled to model the propeller’s physical rotation. The present study is performed in transient format and 3D.
Conclusion
As shown in the obtained results, the generated bubbles generated due to cavitation, cover the blades’ suction side entirely and a bit of trailing edge. This indicates that the rotational velocity of the propeller (1500 rpm) is very high, causing the super cavitation phenomenon to occur on the propeller surface.

Aiyana Cassin –
The results from this tutorial seem very insightful. How does the propeller’s rotation affect cavitation and the final results?
MR CFD Support –
The rotation of the propeller significantly affects the cavitation phenomenon as it creates low pressure regions on the suction side of the blades due to the centrifugal forces. As the rotational velocity increases, these low-pressure regions can lead to cavitation, where vapor bubbles form and, upon collapse, potentially damage the propeller blades. The final results help in understanding where cavitation is likely to occur and to what extent, which is essential for optimizing propeller design and operation condition.
