In the present paper, the influence of longitudinal grooves placed on tubes is investigated for different configurations in tandem for three Reynolds number. Each cylinder has two grooves on the external surface at 90° and 270° degrees. The experiments are carried out using a subsonic wind tunnel. The pressure distributions along the tubes are determined for a variation of the azimuthal angle from 0 to 360 degrees. The drag and lift forces are measured using the TE 44 balance. The results show that the upstream cylinder pressure is greater than for second one. There is a difference in the pressure coefficient as well as the pressure drag for configuration smooth-smooth and grooved-grooved.
