Improvement and Validation of the Computational Aeroelasticity Code ENS3DAE

Abstract

The heightened awareness of the importance of fluid-structures interaction has lead to the development of several tools for addressing such issues. One continually developing tool, ENS3DAE has been adopted for use by several researchers and engineers. In the interest of increased generality, additional capabilities have been implemented into the software. Of these new improvements, the ability to generate a static aeroelastic solution to a two-dimensional airfoil problem using different grid topologies has been successfully completed. Originally written to use H-type grids, ENS3DAE was not able to aeroelastically deflect the two degree of freedom airfoil. After small logic modifications and adjusting a standard input file, a reasonable static aeroelastic solution was obtained. Future plans include validation of the current work and development of a dynamic aeroelastic, pitch & plunge case for the NACA airfoil.
