Experimental and Numerical Investigation of the Erosive Potential of a Leading Edge Cavity

Abstract: This paper presents a joint experimental and numerical analysis of the erosive potential of an unsteady cavity that develops at the leading edge of a two-dimensional hydrofoil and periodically sheds vapour clouds. From an experimental viewpoint, the erosive potential was characterized by pressure pulse height spectra. The hydrofoil was equipped with eight pressure sensors made of PVDF piezoelectric film that allowed the measurement of flow aggressiveness at different locations along the hydrofoil chord. It was… Show more

“…The model upgrade is described in a paper of Leclercq et al [9], where all of the vapor structures, even those not in direct contact with the wall, were considered. In the paper by Carrat et al [10] the results of numerical analysis, including the amplitude and frequency of the pressure waves, were presented and validated experimentally. Based on their findings, Schenke and Terwisga [11] proposed a model of forecasting the erosion threat where energy generated by the vapor structures is conserved and transferred to the wall surface via the pressure wave released after the collapse.…”
