Numerical Simulations of Interaction of Inviscid and Viscous Incompressible Flow with a Vibrating Profile

Popis výsledku v původním jazyce

The work deals with a numerical solution of the interaction of two-dimensional incompressible flows and a freely vibrating profile with large amplitudes. The profile with two degrees of freedom can oscillate around an elastic axis and in the vertical direction. The motion of the profile is described by two nonlinear ordinary differential equations solved numerically using four-order Runge-Kutta method. Numerical schemes of the finite volume method are applied on a structured quadrilateral C-mesh. The method of artificial compressibility and a time marching method are used for steady state computations, which precede the unsteady solution. Dual-time stepping method is employed for numerical solution of unsteady simulations. Deformations of the computational domain due to the profile motion are treated using the Arbitrary Lagrangian-Eulerian method. Numerical scheme used for unsteady flow simulations is implemented in a form satisfying the geometric conservation law.
