Characterisation and validation of a pulsating jet erosion test
, 2007 This study focuses on the further development of a new method of liquid erosion testing by means of a pulsating jet erosion test (PJET). The method was validated in comparison to existing test procedures. Parameters regarding velocity, length and diameter of the jet were evaluated by optical observation through a real-time triggered camera with a high ...
