Simulation of Influence of Mechanical Elements on Karman Vortex Street Parameters

This work presents the results of numerical modeling Karman vortex street generation performed with ANSYS/FLUENT package application. The influence mechanical elements located downstream bluff body on frequency has been found during earlier laboratory investigations. Five various geometrical configurations have tested. Considerable differences in pictures distributions pressure, horizontal and vertical velocities appeared for configurations. Qualitative as well quantitative are presented paper. They confirm significant dependence parameters meter configuration.
