Abstract

Theoretical lamb and shear waves interface shear concentration coefficients values (ISCC) for steel - ice layered systems are predicted and superimposed to its correspondent ultrasonic dispersion curves. Those ultrasonic modes with high ISCC values are expected to enhance possible non-thermal de-icing capabilities as long as enough energy is provided to the system. As ice thickness increases, lamb waves generate up to 140% increases in ISCC values compared to that provided by shear waves, for a phase velocity range between 1 and 7Km/sec. The modes with higher ISCC for different ice thickness are identified. The theoretical dispersion curves used to evaluate the conceptual proposed de-icing system are experimentally acquired and compared to predicted results. The ultrasonic modes experimentally obtained match the theoretically predicted ones with a maximum error of 8%.
