In the present study, the effect of nano Al2O3 and nano graphene ceramic additives in optimizing performance and improving thermophysical properties of aircraft anti-icing/de-icing fluids was investigated. Nanoparticles were characterized by TEM, SEM and XRD methods. The thermal conductivity, surface tension and dynamic viscosity of the hybrid nanofluids were experimentally assessed for temperatures between 253 and 303K and results were compared with some existing theoretical models. Results revealed that the thermal conductivity properties and thus the efficiency of aircraft anti-icing/de-icing fluids are improved by the addition of nanoparticles. Considering the performance of the aircraft anti-icing/de-icing fluids, increasing the surface tension of the fluid helps to improve its performance in covering the aircraft surfaces against the precipitation of super cooled raindrops and snow, resulting in better performance of aircraft anti-ice/de-ice fluid. Based on the results of measuring the dynamic viscosity of graphene-Al2O3/ aircraft anti-icing/de-icing -water hybrid nanofluid, the addition of nanoparticles in the volume fraction ranges from 0 to 0.5%, in addition to increasing the viscosity, show non-newtonian behavior Shear-thinning nanofluid the base, which is the main requirement for the performance of the aircraft anti-icing/de-icing fluid. However, at higher concentrations, the hybrid nanofluid shows a tendency to non-Newtonian shear-thickening behavior. Therefore, the addition of these two types of nanoparticles in volume fractions below 0.5% helps to enhance the performance of aircraft anti-icing/de-icing fluid.
