Wind-load, pressure and velocity measurements: post processing and discussion

Abstract

Abstract. Because of the practical importance of bluff bodies subjected fluid flow, fluid dynamics around two-dimensional bluff bodies, especially circular cylinders, has been studied in light of three major parameters, namely flow-induced force, surface pressure and wake. Though all the three are interrelated, the first two are the integrated behavior of flow velocity around the cylinder. Thus measurements of flowinduced forces, surface pressures and velocity fields are very important in the engineering discipline. This paper discusses force and pressure measurement results for two circular cylinders at gap-spacing ratio T/D varied from 0.1 to 5 and the attack angle α from 0° to 180° where T is the gap width between the cylinders and D is the diameter of a cylinder. Post processing of pressure and force signals is also elaborated.
