Abstract
This paper describes an experimental evaluation of available drag correction formulae and theories for blockage effects applicable to two-dimensional rectangular cylinders immersed in a low-turbulence uniform flow. It is observed that empirical formulae are functions of the afterbody length and that Maskell’s theory has the tendency to overestimate the correction.Keywords
