Simulation of the flow around an oscillating cylinder with adaptive lattice Boltzmann methods
Simulation of the flow around an oscillating cylinder with adaptive lattice Boltzmann methods
As an alternative to the popular approach of solving the Navier-Stokes equations on unstructured, triangular meshes, we utilize in here primarily the self-developed parallel adaptive lattice Boltzmann code AMROC-LBM to study laminar and turbulent flow over an oscillating and rotating cylinder in two space dimensions at Reynolds number 1322 and 6610, respectively. The method is implemented on a dynamically adaptive Cartesian finite volume grid and considers geometrically complex boundaries with a level-set-based ghost-fluid-type approach, making the code well suited for moving structures. Predicted vortex shedding downstream is found to be in good agreement with available experimental results. A direct comparison to the commercial code XFlow shows that AMROC-LBM provides more reliable predictions in shorter computational time.

Abstract
As an alternative to the popular approach of solving the Navier-Stokes equations on unstructured, triangular meshes, we utilize in here primarily the self-developed parallel adaptive lattice Boltzmann code AMROC-LBM to study laminar and turbulent flow over an oscillating and rotating cylinder in two space dimensions at Reynolds number 1322 and 6610, respectively. The method is implemented on a dynamically adaptive Cartesian finite volume grid and considers geometrically complex boundaries with a level-set-based ghost-fluid-type approach, making the code well suited for moving structures. Predicted vortex shedding downstream is found to be in good agreement with available experimental results. A direct comparison to the commercial code XFlow shows that AMROC-LBM provides more reliable predictions in shorter computational time.
