The present paper offers a numerical model which can be applied for the simulation of wave height distribution on a 2-D horizontal soft mud layer. The model is based on mild slope equations and it includes combined wave refraction, diffraction, reflection and breaking. The high energy dissipation of wave height due to the presence of fluid mud layer has also been simulated. Wave height attenuat...

cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. usually failure of cylindrical tanks leads to serious consequences. during the past earthquakes such as 1964 alaska and 1999 turkey seismic performance of cylindrical tanks revealed that tanks are seismically vulnerable. therefore, evaluation of seismic performance of these str...

in this paper, a two-dimensional reynolds averaged navier-stokes (rans) model is developed to simulate the shoaling, breaking and overtopping of a solitary wave over a vertical breakwater. turbulence intensity is described by using a k turbulence closure model and the free surface configuration is tracked by volume of fluid (vof) technique. to validate the numerical model the simulation result...

Two-dimensional potential flow of the ideal incompressible fluid with free surface and infinite depth can be described by a conformal map of the fluid domain into the complex lower half-plane. Stokes wave is the fully nonlinear gravity wave propagating with the constant velocity. The increase of the scaled wave height H/λ from the linear limit H/λ = 0 to the critical value Hmax/λ marks the tran...

As a contribution to deterministic investigations into extreme fluid surface waves, in this paper wave profiles of prescribed period that have maximal crest height will be investigated. As constraints the values of the momentum and energy integrals are used in a simplified description with the KdV model. The result is that at the boundary of the feasible region in the momentum-energy plane, the...

In this paper we present techniques for the real-time simulation and rendering of liquids. Appropriate approximations to a full 3D simulation are applied to reduce the numerical complexity. Fluid flow is described by the 2D Navier-Stokes equations; wave effects are represented according to the wave equation for shallow water waves on a height-field. A novel mechanism for coupling flow and wave ...

The linear stability of finite-amplitude interfacial waves in a two-layer fluid is investigated for superharmonic disturbances on the basis of the Euler set of equations. In the previous study (J. Fluid Mech. 2006, vol.547, p.175), the author proved analytically for surface waves that the superharmonic instability first occurs when the wave energy density becomes stationary as a function of wav...

using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. in this work two-dimensional incompressible laminar flow of a nanofluid e...
