Abstract

A finite element method for solving of the Euler and Navier-Stokes equations is used to study the unsteady aerodynamics of a two-dimensional canard-wing aerodynamic interference. The method used a discontinuous finite element method for spatial discretization and an explicit Runge-Kutta time integration for temporal discretization. The problems of a flow over an airfoil with/without viscosity, a flow over a pitching airfoil, and an airfoil-vortex interaction are tested to show the accuracy of the proposed numerical method. Finally, the results of two-dimensional canard-wing aerodynamic interference in steady and unsteady transonic flows are shown to demonstrate the robustness of the numerical algorithm, and qualitative and quantitative aerodynamic influence of one airfoil on the other.
