Optimizing Gridded Heater Arrangements in Anti-/De-icing Systems through Multiphysics Thermal Simulation

Abstract

The electro-thermal system in anti-/de-icing systems, known for its reliability, is often favoured despite its notable drawback—high power consumption. Seeking to mitigate this issue, the adoption of a gridded heated surface emerges as a promising avenue for energy optimization. In this study, a finite difference method is employed to meticulously examine heat transfer across a selected surface with defined material properties. The simulation specifically investigates heat conduction under various boundary conditions, considering scenarios where a cold surface is either partially or fully heated in the presence of an ice cover. The discourse in this paper delves into the examination of different geometries of heating elements, assessing their impact on critical parameters such as overall power consumption, heating time, performance, efficiency and other relevant factors. By systematically analysing these variables, the study aims to offer insights into the efficacy of gridded heated surfaces as an energy-efficient alternative within electro-thermal systems. This research contributes to the ongoing quest for more sustainable and resource-conscious solutions, offering a nuanced understanding of how gridded heaters can optimize energy usage while maintaining the robustness associated with electro-thermal heating techniques in anti-/de-icing systems.
