Wavelet analysis of experimental results for coupled structural–hydraulic behavior of the EURISOL target mock-up
During test runs of the The European Isotope Separation On-Line (EURISOL) target mock-up performed in December 2008, data were recorded for strain gages and for acceleration sensors. In this paper, the applicability of wavelet analysis for detecting the onset and the status of flow-induced cavitation is investigated for the first time. Even under noisy conditions, the detection of incipient cavitation was possible when combining measurements with data from structural and fluid dynamic simulations. The distribution of coefficients of suitably selected wavelets yields a quantitative measure for the extent of cavitation in the EURISOL target mock-up under representative flow conditions. Withou…
Detection of a structural impact in liquid metal flow during test runs of the EURISOL target mock-up
Abstract The many possible applications of Liquid Metal (LM) technology promise improved thermal efficiency, which can provide much-needed impetus to finding solutions for the growing world energy needs, as well as increasing the accuracy and power of certain delicate scientific apparatus used in the materials and biological sciences. The development of appropriate safeguards and instrumentation is critical to continued progress in this area of technology. During the hydraulic test of the EURISOL liquid metal target, a component failure was registered by the instrumentation; its detection in the presence of liquid metal flow was critical to ensuring the safety of both the personnel and the …
