Mass transport modelling through porous media is typically characterized by complex physics and geometry. In the particular case of radionuclide transport, modelling for radioactive waste repositories, an additional level of complexity, and thus uncertainty, originates from the long time frames involved. Performing a safety analysis of a radioactive waste disposal system requires therefore ...

RFSP-IST (Reactor Fueling Simulation Program) is a computer code used for the full-core neutronics design and analysis of CANDU® reactors. RFSP-IST calculates the static flux and power distributions in the core by solving the neutron diffusion equation in two energy groups. For validation purposes, results from RFSP-IST are often compared with those from other codes. This paper documents the ...

In an earlier work we developed a finite element bidomain model of an aplysia abdominal ganglion in order to estimate the sensitivity of this contrast mechanism to changes in cell membrane conductance occurring during a gill-withdrawal reflex. We used our model to determine both current density and magnetic potential distributions within a sample chamber containing an isolated ganglion when it ...

A successful development of an effective quench detection and protection method for a high temperature superconducting (HTS) coil based on a HTS coated conductor tape lays on a thorough understanding of its slowly propagating, three-dimension (3D) quench behavior. Toward this goal, a 3D micrometer scale finite element (FE) thermo-magnetostatic HTS tape model is developed and implemented in ...

The computer simulation with COMSOL Multiphysics has become a widely used technique for the study of various problems in the field of plasma physics. Despite the increasing performance of computers, fully three-dimensional particle simulations still have got extremely high demands on hardware and computer time. Although many problems could be solved by fluid models, results obtained by these ...

The fabrication of piezo aluminium composite modules for sensor and actor applications with mass production technologies is in the scope of the SFB/Transregio 39 PT-PIESA project funded by the (German Research Foundation). After forming of cavities with a width of 0.3 mm into aluminium sheets by micro impact extrusion and the insertion of 0.25 × 0.25 mm2 piezo rods, a joining of the rods into ...

In this paper we introduce a elastic and hyperelastic model to describe the pressure dependent material stress in joint cartilage. We used the pressure dependent E-modulus E = f(s) to calculate the material stress. E = f(s) is a degree 4 polynomial . The indentor was pressed 0.4 mm into the tissue. The results show that the maximal stress at the contact zone between indentor and cartilage ...

In this work an innovative wind power generation in urban areas is proposed. The generation system substitutes the roof of the building and it consists of a static part, the stator, and a moving part, called impeller, which is a centripetal turbine with vertical axis of rotation. Since the objective is to conveying the air flow in the stator, the logarithmic spiral has been chosen as the shape ...
