Effect of the upstream cylinder shape on the flow around the downstream rectangular object in tandem configuration

Abstract

Abstract The paper presents an experimental investigation of air flow around bluff bodies in tandem configurations. The first one concerns two square cylinders and in the second one a triangular cylinder was used as an upstream object. Experiment was performed for two different Reynolds number for the fixed distance between bluff bodies. To have an insight into the fluid flow, particle image velocimetry method was used. Particular attention was paid to examine the effect of the upstream cylinder shape on the flow around the downstream body.
