Rayleigh type waves on a cylindrical surface

WebAug 17, 2015 · Many years later, Sharma et al. (1990, 1991) deduced the frequency (dispersion) equation for Rayleigh type surface waves on a model consisting of a liquid layer lying over a solid layer which itself is underlain by a solid half-space. WebResults show that the melting rate is the same for all regions of the cylinder for a low Rayleigh number, while it intensifies at the top half of the cylinder for a moderate Rayleigh number. Also, existence of strong unstable flow in the bottom portion of the cylinder at a Rayleigh number of 106 causes the melting rate to keen after a definite ...
