Localised energy concentration -- WO 2014135881 A1 - Publication date: Sep 12, 2014 - Filing date: Mar 6, 2014
ABSTRACT
A method of producing a localised concentration of energy comprises creating a shockwave (16) propagating through a non-gaseous medium (4) so as to be incident upon a boundary (10) between the non-gaseous medium (4) and a gaseous medium (6) formed by at least one hole (8) in a barrier (2) separating the non-gaseous medium (4) from a gaseous medium (6). This forms a transverse jet on the other side of the hole (8) which is incident upon a target surface (12) comprising a depression (14) which is spaced from the barrier (2) in the gaseous medium (6). An apparatus for producing a localised concentration of energy is also provided.
