Campi Flegrei caldera is a good example of the most explosive volcanism on the Earth, a potential source of global catastrophes. It has the advantage that the most interesting structural details and main volcanic features appear located at shallower depth, making it a natural candidate for a deep drilling project aimed to understand the volcanic structure. The CFDDP project, aims to understand ...

Semi-aerobic landfill has interesting structure that passively provides the atmospheric oxygen into landfilled waste due to the heat convection generated by the decomposition of landfilled waste. There are limited studies on the mechanisms of the oxygen transport. This paper presents the governing equations and parameter estimation methods for the numerical simulation of the gas fluid flow and ...

The assurance of mass consistency in constructing 3-D atmospheric velocity fields is important when developing accurate numerical simulations. The implementation of a mass consistent wind field is typically undertaken using available meteorological data obtained from instrumented towers and remote sensors. In this study, two methods are presented and compared for constructing 3-D mass ...

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import “realistic structures” from geologic samples scanned by means of computer tomography (CT) as stl-files into COMSOL ...

Theoretical and experimental studies on the rotation of rigid inclusions under simple shear flow have typically considered infinite width shear zones and perfect attachment of inclusion to the matrix. According to these models, during progressive simple shear a coherent object would continuously rotate synthetically, which is not the case in many natural ductile shear zones. In this work we ...

Many theoretical studies concerning lava tubes focus on the thermal disturbances generated on the earth surface. Recently a solution was suggested, where a lava tube located at a great depth h in the soil, where the ratio between h to the major axis of the ellipse a is higher than 10. However, lava tubes more frequently are located at shallower depths. In this work we ...

In this work, we present a number of scoping calculations that have been carried out to design an in-situ redox experiment (Figure 1) focused on assessing potential changes in the pH and redox conditions and in the buffering capacity of the Olkiluoto bedrock (i.e. the site for the Finnish spent fuel repository). A characteristic of these models lies in the need to integrate prior information, ...

In this work, COMSOL Multiphysics was used to develop a model to investigate the degree of saturation in sloped terrain. The model was validated via laboratory experiments incorporating Lan’s man-made rainfall slope model test. The validated model was used in an actual case study to simulate the Maokong Landslide.

A 3D finite element model was used to evaluate the time dependent ground deformation and the stress change caused by a pressure source embedded in a viscoelastic medium. In volcanic areas, the presence of inhomo-geneous materials and high temperatures produce a lower effective viscosity of the Earth's crust which calls for consideration of the thermal regime of crustal volume surrounding the ...
