Here we aim to advance geomagnetic modeling approaches using COMSOL Multiphysics® software and improve the degree of detail that can be obtained from the measured magnetic field. First, we carried out benchmark tests by comparing the computed results using the widely used analytic solutions for rectangular bodies with arbitrary direction of magnetization with those from the AC/DC Module of ...

The radiation force effects on the surface displacement can be calculated by solving the Navier-Stokes equation with appropriated boundary conditions. The surface deformation can be described by the radiation pressure as well as those forces due to gravity and surface tension. We used the photomechanical mirror (PM) method to measure the time-evolution of the nanometer deformation generated on ...

A three-dimensional mathematical model under stationary conditions have been established to understand the corrosion of carbon steel cylindrical samples immersed in flowing NaCl solution through an annular duct. The migration, diffusion and convection mass transfer mechanisms were solved using the Nernst–Planck equation coupled to the Navier-Stokes equation. A corrosion model based on the mixed ...

Microwave sensing and monitoring is very attractive for biological applications because of their sensitivity to water and dielectric contrast. Direct detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is considered as a problem of a great importance. Nowadays, however, microwave technique for localized testing biological ...

Plasma technology has potential applications in a wide range of areas, such as microwave reflectors/absorbers, material processing, sterilization and chemical neutralization. The knowledge about the fluid behavior in such systems has a central role, since the stability of the flow in the region of the electrical arc is essential for the development of a well-behaved torch. In this work, a ...

Radioactive waste repositories include barriers that work to contain the waste, thereby protecting human health and the environment. In deep geological disposal systems, barriers include the natural geological barrier and the engineered barrier system (EBS). The ability of the EBS to limit groundwater flow is important and optimized design solutions are often sought by means of numerical ...

We have created and optimized a multiphysics model using COMSOL Multiphysics® software that incorporates the Free and Porous Media Flow and Heat Transfer in Porous Media interfaces to simulate the temperature profile of a chromatographic system under external heating and cooling conditions. In chromatography, a liquid mobile phase is pumped through a column containing a stationary phase made ...

The objective was to make a visualisation application for the pupil's lab of the University of Applied Sciences Bielefeld. The application serves as a supplement for a workshop. It should provide a better understanding of a fuel cell, to visualize important influences and collect first experience with a simulation. To achieve this objective, a model of the fuel cell is created. The ...

Recently, the researchers usually use the hydrodynamic Drude model (HDM)to investigate the nonlocal optical response of metallic nanostructure. The advantage of the HDM is easy to implement numerical calculation for larger and more complex shaped nanoplasmonic structures. For the HDM, it is predicted that the nonlocal response blueshifts the resonance peak, modifies the electric field ...

Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx applied at each load cell. Strain gauges were located on a diaphragm forming one face of the load cell. The ...
