Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

Types of cavitation: Viscous effects on inception of sheet cavitation

 

Cavitation inception takes place when nuclei are exposed to a pressure lower than the critical pressure. But the minimum pressure around a foil or propeller blade occurs on or close to a solid surface, where a boundary layer exists. This boundary layer has an effect on the pressures encountered by the nuclei. These effects are summarized as viscous effects on cavitation inception, because the boundary layer is a viscous phenomenon.
