- Abstract:
- The most important uncertainty component of the pressure step signal determined at the end-wall of the shock tube is associated with the uncertainties of the shock wave velocity and the arrival time of the shock front. Both are determined using a time-of-flight method and are therefore greatly affected by the errors in the detected times of the shock wave passages over the side-wall pressure sensors installed along the shock tube. This paper introduces a method for an automated correction of the systematic errors due to non-ideal dynamic response of the side-wall pressure sensors.
