In this paper, an integrated model for ocean waves propagating over a submerged coastal structure, based on COMSOL Multiphysics, is presented. In the model, Navier-Stoke Equation is solved for the wave propagation and Biot’s poro-elastic model is solved for the porous seabed. The new feature of this model is to integrate both wave and soil models into one model. This can be achieved within ...

In solid mechanics, there is considerable interest in achieving “invisibility”. The applications in mechanics include protection of structures and parts of structures from potentially harmful transient waves and steady state vibrations. A suggested large scale application is that protection against seismic waves from earthquakes could be achieved by using cloaking to re-route the waves around ...

New geothermal energy sources hold promise for the future. Deep submarine geothermal energy related to hydrothermal vents is emerging in many places along the oceanic spreading centers. Shallow submarine geothermal systems are found near to continental platforms. We present the initial development of mathematical models to simulate the energy transport in submarine systems. A model for the ...
The Effect of the Disintegration of Chemical Stratification on the Time-dependent Behavior of the Earth’s Mantle
A. Galsa, and M. Herein
Based on recent results from seismology, geochemistry etc. the distinct chemical character of the D’’ layer (lowest part of the mantle around the Earth’s core) has appeared unequivocally. Numerical calculations have been carried out to investigate the effect of the disintegration, mixing and homogenization of the dense D’’ on the time-dependent behavior of mantle convection. A ...

Topographic effects on magnetotelluric responses may be severe on rugged terrains. Finite elements simulation is a valuable tool to quantify this effect, due to its capability to match real morphologies. To do the estimate of the distortion, the AC/DC Module of COMSOL has been employed, using a model of homogeneous resistivity on which a DEM (Digital Elevation Model) profile of the Deep Freeze ...

We present numerical models and field data that aid understanding of volcano-tectonic processes related to the propagation of inclined sheets and dykes under a stress field resulting from the inflation of a shallow magma chamber. Structural field data from the classical Cuillins cone-sheet complex (Isle of Skye) show that sheets have a constant average dip angle (45°), with pure dilational or ...

The capture and storage of CO2 in deep geological formations is one of the proposed solutions to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. In general, four trapping mechanisms are expected, which are of increasing importance through time: (1) structural, (2) residual ...

Due to increased demands on groundwater accompanied by increased drawdowns (ca. 2-3 meters/year), technologies that use alternative water resources have been suggested for Dhaka City, Bangladesh. Preliminary studies show that managed aquifer recharge (MAR) would help in optimal use of available water resources and to reduce adverse effects of pumping in the Dupitila aquifer of the city. In this ...

We have developed a numerical model to represent the effect of injection test in unsaturated porous and fractured rock mass. The test was conducted at the LSBB (Laboratoire Souterrain à Bas Bruit) site close to Rustrel, Vaucluse, France in the field of the French ANR project called “HPPP-CO2”. The results underline the impact of fractures on the hydro-mechanical response of the rock-mass. Indeed ...

The Levant has been repeatedly devastated by numerous earthquakes since prehistorical times. In order to understand the role of the dynamics of the water bodies in triggering the deformations in the Levant basin, a new theoretical thermo-mechanical model is constructed and extended by including a fluid flow component, in COMSOL Multiphysics simulation environment. The latter is modeled on a ...
