Abstract:In this study, the numerical investigation of free dynamic response of a rigid, symmetric airfoil having two coupled degrees of freedom is performed. The airfoil is excited using two different mechanisms. Firstly, a mechanical excitation scenario is simulated using initial conditions for both the degrees of freedom. Dynamic airfoil response in terms of amplitudes of oscillation is recorded under no flow as well as uniform upstream flow conditions. In the second scenario, an upstream flow perturbation is introd… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
