Numerical investigation of the flow past an oscillating cylinder in a non-inertial reference frame

41040

In this study, the flow past a cylinder which is forced to oscillate in a free stream is numerically investigated using a solver developed within the framework of the open-source toolbox OpenFOAM. Governing equations are written in the non-inertial reference frame fixed to the cylinder and solved using the finite volume method. Flow is assumed to be incompressible, unsteady and two-dimensional. Harmonic oscillation of the cylinder is considered separately for each degree-of-freedom (heaving, surging and pitching). By spanning several oscillation frequencies, the lock-in behavior is captured. The agreement obtained in the moving cylinder problem demonstrates the convenience of the approach in the general flow simulations of moving rigid bodies.
