... and Trytten8 The drag, inertia, and the lift coefficients for a smooth cylinder (~ = DL/vT = 4000) are shown in Figs. 1 through 3. Clearly, the independence principle does not hold true for sinusoidally-oscillating flow about yawed smooth cylinders. Both the drag and inertia coefficients increase...

... is restricted to an abstract of not more than 300 words. APPROACH Heideman, et al (2) show a plot of the post- critical steady flow drag coefficient as a function of relative roughness, k/D,wherekisthe height of the roughness elements and D is the smooth cylinder diame- ter. It is reproduced here as Fig. 1...

... was accomplished by hanging loads in the middle of the cylinder after setting both gages to sense only the transverse force. The calibra- tion was checked for horizontally-applied loads through the use of a simple pulley and weight system. Experiments were first conducted with 5 and 6.5 inch smooth cylinders...

The Morison equation and some basic results for the drag and inertia coefficients in laboratory and ocean tests are reviewed. New results...

... roughness on the force experienced by cylinders in waves, as the results published of previous laboratory studies have always related to smooth cylinders. In the present study an attempt was made to simulate rigid marine growths such as barnacles and limpets by attaching garnet paper to the surface...

...-known fact that organized, uniform roughness in steady flow about a cylinder precipitates the occurrence of the critical regime and gives rise to a minimum drag coefficient which is larger than that obtained with a smooth cylinder. This is partly because of the transition to turbulence of the free shear...
