Abstract

Measurements of sectional r.m.s. lift coefficients for circular cylinders under similar conditions at sub-critical Reynolds numbers using (a) multiple pressure transducers with direct on-line integration and (b) pneumatic spatial pressure averaging and only two pressure transducers gave results which are in good agreement.
