The document deals with reporting of a new series of experimental data measured in the PIPER facility.

Abstract

The document deals with reporting of a new series of experimental data measured in the PIPER facility. PIPER was installed at the Scalbatraio Laboratory managed by IIN (Istituto di Impianti Nucleari) of University of Pisa. PIPER consisted of a pressure vessel equipped with electrical heaters and rupture nozzle, other than suitable instrumentation (typically temperature and pressure transducers). Namely original instrumentation was developed to measure the jet thrust, the jet impingement loads and the load on internal components following the break opening and the propagation of the depressurization wave upstream from the rupture into the vessel. In this report, experimental data of blowdown are documented to constitute the basis for setting up an original procedure for measuring the Two-Phase Critical Flow (TPCF) based on pressure and pressure drop measurements as well as jet thrust measurement. The data base allowed the development of the BLOWAES software.
