Groundwater-bearing geological layers respond to and modify the surface expressions of magmatic activity, and they can also become agents of volcanic unrest themselves. Interpretations of unrest signals as groundwater responses to changes in the magmatic system can be found for many volcanoes and include a wide range of phenomena and suggested processes to explain them (e.g., Newhall et al., ...

Droplet flow at microscopic scale is often used to enhance many pharmaceuticals and industrial processes (i.e. liquid–liquid micro-extraction, nanoparticle synthesis, slow reactions in microfluidic devices, etc.). In all these processes, the mass transfer rate, at the interface between the droplets and the surrounding fluid of diluted reactants plays a key role. This work at analyzing ...

In this report I study the airflow through ventilation ducts. By numerical simulation, the so-called k-factor has been estimated. The k-factor is the quotient of the airflow volume and the square root of the pressure drop over the duct. A two dimensional axial symmetric model has been used to simulate an iris damper connected to a straight pipe. A three dimensional model has been used to ...

Chemical engineering students and practitioners need an understanding of fluid flow and heat transfer inside heat exchangers. Because the flow within plate heat exchangers is difficult to visualize, we developed COMSOL Multiphysics® simulations of plate heat exchangers for students to study alongside a physical heat exchanger in a laboratory setting. Simulative experiments allow students to ...

COMSOL Multiphysics® software is used to understand the difference in behaviour of two Magnetic Barkhausen Noise (MBN) probes. The dipole probe has to be physically rotated to sample the angular distribution of the MBN. The tetrapole probe uses vector superposition to rotate the magnetic field without probe motion. Using the AC/DC Module and non-isotropic material properties, it was found that, ...
