High performance computation of a lagrangian approach for turbulent flow investigations around cylinders with different surfaces

Abstract

The Discrete Vortex Method finds application in engineering contexts, primarily for the estimation of hydrodynamic forces in fluid-structure interaction within a two-dimensional domain. In recent years, this method has been extended with solutions that incorporate turbulence and rough surface effects. This paper reports advancements resulting from parallel programming using OpenMP, enabling the implementation of Lagrangian methods that were previously computationally intensive. Additionally, partial results of investigations into the control of vortex shedding by changing the roughness of the body are also presented.
