Year: 2025
Type: article
Abstract: The electro‑thermal anti/de-icing systems have high heating efficiency and relatively simple structures， marking them as a key development direction for future icing protection. Existing simulation algorithms for electro-thermal de-icing seldom delve into comprehensive ice accretion-melting-deicing models that account for ice shedding. Therefore， the detachment behavior of ice layers during the heating process requires in-depth research and discussion. This paper physically models the phenomenon of ice shedding， incorporates the detachment behavior of ice layers during heating， improves the existing mathematical model for electro-thermal de-icing calculations， establishes an ice accretion-melting-deicing model for electro-thermal de-icing systems， and conducts numerical simulation， verification and optimization analysis of electro-thermal de-icing considering ice shedding. Through multi-condition de-icing numerical simulations of a specific wing model， it is found that ambient temperature can serve as a factor for adapting the electro heating anti/de-icing strategy to the environment. An optimization of heating heat flux density and heating/cooling time is conducted for the wing de-icing control law under the calculated conditions. The improved electro-thermal de-icing model and algorithm developed in this paper provide solid technical support for the design of electro-thermal de-icing systems.
