Abstract

A free piston shock tunnel (FPST) is one of the most useful test facilities for generating high enthalpy flow. Therefore, the FPST has been intensively used in conjunction with the development of re-entry vehicles and SCRAM jet engine. In this study, piston motion in a compression tube of a free piston compression tube was measured continuously in order to obtain the quantitative piston speed of a FPST by means of a high resolution interferometer and results were compared the computation based on concept of " Tuned Operation Condition"which uses a quasi-1D ENO scheme with 4th order accuracyGood agreement was obtained between measured numerical results and predictions. A double exposure holographic interferometric visualization of a shock wave released from the compression tube was carried out.
