The effect of freestream turbulence on the flow past a circular cylinder (tube) was studied experimentally for Reynolds numbers between 2 x 104 and 6 x 104. Investigations were carried out for uniform (non-turbulent) flow and for turbulent flows having turbulence intensities between 1.3 and 4.1%. The variations in the pressure forces and shedding frequencies were found to be related to the variati

This paper concerns an experimental investigation of the flow around and pressure forces on fixed (non-vibrating) rectangular cylinders at angles of attack 0° - 90°. Pressure forces and moments for cylinders with side ratios B / A = 1, 1.62, 2.5 and 3 (shortest side A = 20 ram) were estimated from measurements of static pressure distributions at mid-span. Wake frequencies and associated Strouhal n
