HIGH PERFORMANCE COMPUTATION OF A LAGRANGIAN APPROACH FOR TURBULENT FLOW INVESTIGATIONS AROUND CYLINDERS WITH DIFFERENT SURFACES

The Discrete Vortex Method is used in engineering applications, mainly for estimation of hydrodynamic forces in fluid-structure interaction in the two-dimensional domain. In recent years this method has been extended with solutions to include turbulence and rough surface effects. This paper reports advances due to parallel programming, OpenMP, to make possible Lagrangian methods that were relatively computationally expensive. Partial results of investigations into the control of vortex shedding by changing the roughness of the body are also presented.
