Method for correction of the systematic errors in detected shock wave passage times in the shock tube

Hernández Castro, Francisco Javier (author), Svete, Andrej (author), Kutin, Jože (author)

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.
