Measurement of crossflow forces on tubes

Abstract

A force transducer for measuring lift and drag coefFicients for a circular cylinder in turbulent water flow is presented. In addition to describing the actual design, requirements for obtaining valid fluid-force test data are discussed, and pertinent flow-test experience is related.
