We are pleased to share that LESSICE participated in the Spoke 6 Workshop held in Pisa on February 18-19, 2025. Organized by Sapienza Università di Roma and Università di Pisa under the 𝐈𝐂𝐒𝐂 𝐈𝐭𝐚𝐥𝐢𝐚𝐧 𝐑𝐞𝐬𝐞𝐚𝐫𝐜𝐡 𝐂𝐞𝐧𝐭𝐞𝐫 𝐨𝐧 𝐇𝐢𝐠𝐡-𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞 𝐂𝐨𝐦𝐩𝐮𝐭𝐢𝐧𝐠, 𝐁𝐢𝐠 𝐃𝐚𝐭𝐚, 𝐚𝐧𝐝 𝐐𝐮𝐚𝐧𝐭𝐮𝐦 𝐂𝐨𝐦𝐩𝐮𝐭𝐢𝐧𝐠, this event focused on multiscale modeling and engineering applications.
During the workshop, our colleague Ubaldo Cella presented the 𝑳𝑬𝑺𝑺-𝑰𝑪𝑬: 𝑴𝒖𝒍𝒕𝒊𝒔𝒄𝒂𝒍𝒆 𝑳𝑬𝑺 𝑺𝒊𝒎𝒖𝒍𝒂𝒕𝒊𝒐𝒏 𝒇𝒐𝒓 𝒊𝒏-𝒇𝒍𝒊𝒈𝒉𝒕 𝑰𝑪𝑬 𝒂𝒄𝒄𝒓𝒆𝒕𝒊𝒐𝒏 𝒔𝒊𝒎𝒖𝒍𝒂𝒕𝒊𝒐𝒏 𝒑𝒓𝒐𝒋𝒆𝒄𝒕, which was selected through cascade funding calls. This initiative aims to advance numerical simulation methodologies for in-flight ice formation on aircraft surfaces, contributing to enhanced safety through improved predictions of aerodynamic performance degradation caused by icing.

❄️ Understanding Ice Accretion: The formation of ice on aircraft surfaces occurs when supercooled water droplets impact the airframe, creating irregular ice layers that negatively affect aerodynamic performance and flight safety.

❄️ Multidisciplinary Approach: Ice accretion is a complex multiphysics and multidisciplinary problem that requires:
✔︎ Aerodynamic flow analysis around complex geometries.
✔︎ Study of droplet trajectories and their impact on the aircraft surface.
✔︎ Thermodynamic modeling of the water layer, phase transitions, and heat transfer between ice and the aircraft structure.
✔︎ High-Fidelity Simulations: The project leverages high-resolution Large Eddy Simulation (LES) methods to improve the understanding and predictive capabilities of icing effects.
✔︎ Computational Challenges: LESS-ICE seeks to automate and enhance computational grid generation, minimizing manual intervention and improving simulation efficiency.
