Abstract [en]

This paper presents experimental work on a new type of transient water jet device. A spark discharge at one focus of a two-dimensional, elliptical, water filled cavity creates a shock wave which converges towards the other focus. There it enters an axisymmetric duct and is converted into a plane shock wave which moves out from the plane of the ellipse. When the plane wave reaches the free surface at the front of the nozzle a water jet is emitted. The Schliereren technique is used to study the process of wave convergence in the cavity. Resulting jet speeds form a simple non-optimized device are also measured. The fundamental idea appears to work and the results are promising, but difficulties remain.
