As part of a larger project called “Healing Water” this thesis project investigated aspects of minimally invasive water-jet drilling as a technology to be used in micro-fracture surgery. Drilling prototypes were developed and tested to gain a better understanding of the potential and the behaviour of high-pressure water jets in conjunction with...

Aseptic loosening is the major failure mode for hip prostheses. Currently, loosened prostheses are revised during open surgery. Because of a high complication rate, this demanding procedure cannot be performed in patients with a poor general health. We are developing an alternative minimally invasive refixation procedure that leaves the...

Abstract - When surgically drilling blind holes in bone using a Water Jet (WJ), control over the resulting depth is a challenging issue of paramount concern. This thesis was part of a project aimed at replacing the awl and mallet technique used in traditional microfracture procedures with an arthroscopic high-pressure WJ instrument is capable of...

The effect of introducing an air film around a submerged water jet is examined in laboratory experiments. The objective is to reduce the friction forces between the water jet and the ambient fluid, making a jet potentially more effective at a larger distance. The test are conducted at a physical scale comparable to dredging practise, contrary to...

Royal Boskalis Westminster nv is an international group with a leading position in the world market for dredging services. In most practical cases a jet installation or a big discharge aperture is used for the fast unloading of a load of sand. When a relative small discharge opening, without the use of a jet installation, is used to unload a...

The safety of a large part of the Netherlands depends on sea dikes. Due to climate change, a sea level rise is predicted. Together with stronger storms and more wave attack, wave overtopping on the current dikes will increase. As a response, crest levels of the dikes need to be raised in order to meet the present regulations for wave overtopping...
