Abstract

Computational Analysis and Study of Atmospheric Ice Accretion on Different NACA Profile Series

Estheru Rani Talasila* and Balaji Ravi

Aircraft icing and ice accretion pose great threat to the safety as the accumulated ice affects the aerodynamic profile of the airfoil hence extensive investigation is being done to understand ice accretion on airfoils. These studies help us understand how lift, drag, pressure and the velocity control is affected due to accumulated ice and how certain measures can be taken to ensure an efficient flight while minimizing risks posed to the safety. This paper focuses on the differences in the aerodynamic parameters on different NACA profiles and how each airfoil is affected by the ice accretion. The computational analysis of this research concentrates on the performance parameters of airfoils of NACA four, NACA five and NACA six digit series on conditions with clear ice, rime ice and without ice for different values of angle of attack. The key research objective of the paper was to investigate how each airfoil is affected under the different icing conditions and compare the results to study ice accretion on different airfoils, namely, NACA0012, NACA23012 and NACA643218. The 2D model of the airfoils was developed with Solid works and Standard K-€ model was used for CFD analysis.
