A linear three-dimensional problem of hydroelastic wave diffraction by a bottom-mounted circular cylinder is analysed. The fluid is of finite depth and is covered by an ice sheet, which is clamped to the cylinder surface. The ice stretches from the cylinder to infinity in all lateral directions. The hydroelastic behaviour of the ice sheet is described by linear elastic plate theory, and the flu...

We first make a note on the use of infimum instead of minimum in Equation 4 of the paper. This is because BT may only exist in the limit. An example is shown in Figure 1, where M is made up of a horizontal sheet and a vertical, cylindrical sheet close to the horizontal sheet’s boundary. The two sheets meet at a non-manifold seam with a circular shape (dotted curve). The shortest exposing tree a...

Abstract We consider problems based on linear water wave theory concerning the interaction of oblique waves with horizontal cylinders in a fluid consisting of a layer of finite depth bounded above by a free surface and below by an infinite layer of fluid of greater density. For such a situation time-harmonic waves can propagate with two different wavenumbers K and k. The particular problems of ...

A two-dimensional free surface flow past a circular cylinder forced to performstreamwise oscillations in the presence of an oncoming uniform flow is investigated at a Reynolds number of R = 200 and fixed displacement amplitude, A = 0.13, for the forcing frequency-to-natural shedding frequency ratios, f/f0 = 1.5, 2.5, 3.5. This study is based on numerical solutions of the special integral form o...

laminar free convection heat transfer from vertical and inclined arrays of horizontal isothermal cylinders in air was investigated experimentally and numerically. experiments were carried out using mach-zehnder interferometer and the fluent code was used for numerical study. investigation was performed for vertical and horizontal cylinder spacing from 2 to 5 and 0 to 2 cylinder diameters respec...
