Axisymmetric wave propagation on a conical shell
Equations are derived to describe the propagation of axially symmetric waves generated at the apex of a conical shell, taking into account he coupling between longitudinal and transverse waves. A form of approximate solution is proposed, based upon the Green's function for wave propagation on a fiat plate but containing several variational parameters, the number of which can be reduced to one i...
متن کاملviscous drag reduction on axisymmetric bodies using helical riblets
a series of subsonic wind tunnel tests was conducted on an ogive-cylinder-flare configuration at zero angle of attack to study the effects of small helical protuberances on viscous drag reduction behavior. the experiments have been carried out on a smooth model and two wire-wrapped models with different spacing between the helical riblet rings, known as pitch length. in the present experiments,...
متن کاملTime-domain analysis of wave exciting forces on floating bodies at zero forward speed
The problem of determining the exciting forces acting on a rigid floating body due to uni-directional waves has been extensively studied. The problem is usually formulated in the frequency domain by assuming that the incident waves are sinusoidal of fixed frequency. Results for more general wave systems may then be found using superposition and Fourier analysis. In this paper, the problem will ...
متن کاملWave drag on floating bodies.
We measure the deceleration of liquid nitrogen drops floating at the surface of a liquid bath. On water, the friction force is found to be about 10 to 100 times larger than on a solid substrate, which is shown to arise from wave resistance. We investigate the influence of the bath viscosity and show that the dissipation decreases as the viscosity is increased, owing to wave damping. The measure...
