Abstract

Spectral methods have been used with great success in numerical simulations of turbulent flows in simple computational domains. In this paper we present the next generation of spectral methods on unstructured and polymorphic domains suitable for addressing the geometric complexity of industrial applications. These new methods are hierarchical and are well suited for computational steering and dynamic Direct Numerical Simulation (dDNS).

Using dDNS we study flow past a flexible cylinder subject to vortex-induced vibrations. We present results for the lift forces and corresponding cross-flow amplitude of cylinder vibration as well results on statistics and flow vizualizations. These results are in good agreement with experimental data unlike previously published results at lower Reynolds number.
