Convective Heat Transfer Effects in Airfoil Icing

Various classic icing codes have been developed and used by the aircraft manufacturers to predict the ice shapes evolution. These codes apply boundary layer integral analysis, based on sand grain roughness, to estimate the convective heat transfer coefficient around the iced airfoil and adopt abrupt transition between laminar and turbulent flow. In the present work, the integral analysis is als...

Study the effect of nano Al2O3 and nano graphene ceramic additives on the aircraft anti-icing/de-icing fluids

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 tempera...

De-icing/Anti-icing Techniques for Power Lines: Current Methods and Future Direction

Atmospheric icing may be problematic for many industries, including electric utilities. The combination of wind and ice could cause damages, sometimes leading to power outages. The January 1998 ice storm has led to the development of several de-icing methods destined to overhead power lines. These techniques are the subject of several technical reports and publications. Furthermore, in the past...
