The profile with two degrees of freedom can oscillate around an elastic axis and in the vertical direction. The profile motion is described by two nonlinear ordinary differential equations. They are solved numerically using four-order Runge-Kutta method. The mathematical model of laminar viscous flow is represented by the unsteady Navier-Stokes equations. Numerical schemes of the finite volume method are applied on a structured quadrilateral C-mesh. The method of artificial compressibility together with a time marching method are used for steady state calculations, which precede the unsteady solution. Dual time stepping method is employed for unsteady numerical simulations. Deformations of the computational domain due to the profile motion are treated using the Arbitrary Lagrangian-Eulerian method.
