Abstract
To further the knowledge of the Shock Induced Spray Process (SISP), an experimental apparatus which simulates Centerline's Waverider thermal spray gun was created which uses an unsteady flow to propel solid particles onto a substrate by the use of a shock wave to produce a coating. Experiments were conducted at a variety of operating supply pressures, firing frequencies, and stand off distances. A qualitative analysis was done using a custom Schlieren system along with a high speed camera. Insight into the flow behaviour in the SISP was established with the definition of six distinct phases. The formation of a bow shock, which is known to be detrimental to the SISP operation, is shown to be more prominent in the cases with higher supply pressure and close proximity of the apparatus exit to the substrate than with changes in firing frequency.
