Abstract:
1. A method for detecting a presence of aberrations within a workpiece having internal walls that define an internal conduit of the workpiece, the method comprising: delivering fluid through the conduit; equalizing the temperature of the workpiece with the temperature of the fluid and maintaining the temperature of the workpiece and the fluid in a steady state condition; measuring one or more conditions of the fluid as it traverses at least a portion of the conduit; mechanically exciting the workpiece causing an excitement event; and identifying whether an aberration is present within conduit or conduit walls based on the one or more measured conditions of the fluid, providing a processor having inputs for receiving electronic data reflective of the temperature condition of the fluid and the excitement condition of workpiece, and wherein the identifying step further includes: correlating any changes in the temperature condition of the fluid data with the excitement event.
