Direct Wave Propagation Analysis For Ice Accretion Assessment On a Composite Plate Using Ultrasonic Guided Waves

Surface ice detection is required in the several industry sectors because ice buildup can pose problems ranging from poor performance to major collapse. As a result, it is critical to control or protect ice formation, particularly in key areas of a structure. This inspires the creation of a sensor-based early ice monitoring system. The current study investigates how direct ultrasonic guided wave propagation interacts with ice layers on top of a composite plate, as well as the effect of ice thickening on ultrasonic wave propagation. As a result, various actuator-sensor pairs were studied experimentally in a MIMO (multiple input, multiple output) arrangement to analyze the influences of various transducer pairs at different frequencies (50 kHz, 150 kHz). Signal processing mechanisms such as detection indicator (DI) have been used to determine the different layers of ice.
