Rayleigh type waves on a cylindrical surface
WebJul 22, 2005 · Rayleigh waves, which are elastic surface waves occurring at the interface between a solid elastic body and vacuum, are investigated. The exact solution of some canonical elastodynamic problems in a circular cylindrical geometry is given, from which the Rayleigh wave contribution is isolated. The dispersion—i.e., the dependence of the … Webthermoelastic cylinder with thermal heat source boundary conditions. Abo-Dahab and Biswas [40] studied the Rayleigh wave propagation with rotation in transversely isotropic thermoelastic medium. The effect of rotation on voids electro-magneto thermoelasticity with theory of energy dissipation was studied by Othman and Hilal [41].

WebMay 1, 2024 · Potto Project. Rayleigh–Taylor instability (or RT instability) is named after Lord Rayleigh and G. I. Taylor. There are situations where a heavy liquid layer is placed over a lighter fluid layer. This situation has engineering implications in several industries. For example in die casting, liquid metal is injected in a cavity filled with air. WebApr 13, 2024 · Therefore, the aspect ratio of the cylinder is Γ = L ̃ / R 0 = 9.01, i.e., twice the critical aspect ratio Eq. ; in this way, the axial undulation caused by the mode with the Rayleigh–Plateau wavelength λ c will produce two necks along the jet, inducing fragmentation into two droplets, as shown in the following.
