Experimental research on ice particle impact on aluminum alloys

Experimental Investigation of the Accretion and Shedding Process on a Heatable Naca0012 Airfoil in Ice Crystal Icing Conditions

“…The influence of particle rotation including melting of ice particles in an airflow with positive ambient temperatures was studied by Kintea et al and Hauk et al (Kintea et al, 2015;Hauk et al, 2016). The impact and fragmentation behavior of individual ice particles on rigid surfaces was the topic of many experimental studies (Guégan et al, 2011;Vargas et al, 2014;Vargas et al, 2015;Hauk et al, 2015;Hong and Moon, 2017;Han et al, 2018;Reitter et al, 2021;Karpen et al, 2021). The collected experimental data supported the development and validation of empirical and physical models (Trontin et al, 2016;Tippmann et al, 2013;Roisman and Tropea, 2015;Kintea et al, 2016a;Roisman, 2022;Senoner et al, 2022).…”

Numerical modelling of ice: Mechanical behaviour of ice under high strain rates

“…Additionally to the shape, (e.g. sphere [17,18] and cylinder [15]), also the impact velocity [19], and the size [20] of ice projectiles are considered main factors for the study of ice impact. However, test data always shows a large scatter, due to the variation of ice projectiles induced during their manufacturing process and the uncertainty of the measurement [17].…”

“…For example, Pernas-Sánchez et al [20] utilized a mass-spring analogous system on a load cell to measure the impact force provided by the ice projectile, while high-speed cameras were used to record the impact process [15,16,19]. Both rigid [15,21] or aluminium targets [18], which have predictable material models, are used to inversely reproduce the ballistic behaviour of ice projectiles. In comparison to monitoring ice projectiles themselves, the recording of the mechanical response of the targets is more practical and applicable thanks to advanced measurement methods [21,22], such as digital image correlation (DIC) techniques.…”
