Book Description
Axial forces were measured on five cylinders at M = 5 for Re = 4,000,000/ft and 37,000,000/ft. The purpose of these tests was to measure the surface drag of the cylinders for various surface protrusion patterns. Using these experimental measurements and data from J.C. Westkaemper, an expression was developed for calculating the average effective drag coefficient of one protrusion in a row of protrusions which are fully submerged in a turbulent boundary layer.
