Abstract:

This paper presents the implementation of Fluent code`s sliding-grid method to carry out unsteady flow simulations of three test configurations i.e., a NACA0012 airfoil pitching harmonically about the quarter chord, an oscillating 3-D wing with NACA0012 cross-section and a helicopter rotor with two blades, cross section of each blade is NACA0012 airfoil, these blades are rectangular and have no twists or tapers. Inviscid calculations are performed for airfoil and Kå-RNG turbulence model is used for wing and rotor simulations. Obtained results qualitatively agree very well with wind tunnel data present in literature.
