Cold and humid environment simulation for de/anti-icing fluids evaluation

Abstract New recommendations regarding the performance of de/anti-icing fluids used on aircraft parked on the ground have been presented by various international organizations such as the Association of European Airlines (AEA) and the Society of Automative Engineers (SAE), and evaluation of fluid behaviour under cold and highly humid conditions is now required. An experimental simulation corresponding to AEA specifications is described as performed in the cold chamber of the Groupe de Recherche de l'Environment (GRIEA) at the Universite du Quebec a Chicoutimi. The methods to insure a high relative humidity level and an appropriate frost deposition rate are demonstrated. A description of the fluid behaviour is offered from a simple numerical analysis supported by results drawn from several anti-icing fluid experiments.
