Pyrochemical process based on molten salt electrorefining is ideally suited for reprocessing spent metallic fuels from Fast Breeder Reactors. In this work, a heat transfer analysis of the Electrorefiner cell was conducted to develop a basic tool for designing of the engineering–scale Electrorefiner. The focus of this work is to find out steady state temperature profiles of cover gas and molten ...

Numerical analysis based on finite element method (FEM) represents a powerful approach to solve electromagnetic problems. For instance, FEM methods have been broadly used to calculate the critical state current distribution in high temperature superconductors of various geometries. In the near future, we intend to develop a tool in COMSOL v3.5a for the analysis of power applications, such as ...
Evaluation of Performance of Enzymatic Biofuel Cells with Microelectrode Arrays Inside a Blood Artery via Finite Element Approach

Florida International University, Miami, FL, USA
Enzymatic biofuel cells (EBFCs) are considered as a promising candidate for powering miniature implantable devices. In order to predict the performance in the human blood artery, we simulated a 3D EBFC chip with highly dense micro-electrode arrays. In this simulation using COMSOL Multiphysics®, we applied the 1) Michaelis Menten equation; 2) Nernst potential equation; 3) Navier Strokes velocity, ...

The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. The block caving technique is based on the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of compact material located in the upper layers because the stress propagation generated by the extraction ...

Most technical systems become smart over time, therefore those systems will have improved safety and comfort functions. An example is a new development by Westfalia-Automotive. A new generation of smart tow bars, equipped with a sensor system, including distance sensors, is able to inform the driver of a car with a connected trailer about vertical and trailing loads. This helps to ensure a ...

Signal processing algorithms for chemical sensing/monitoring have been subject of considerable research interest in the recent years mainly due to their diverse applicability. When the concentration of chemical agent is small, the dispersion of particles is governed by stochastic differential equations describing more complex motion mechanisms such as Brownian motion. In this paper we propose ...
Viscous damping of a periodic perforated MEMS microstructure when the Reynolds’ equation cannot be applied: Numerical simulations

Department of Mechanical Engineering, SUNY Binghamton, NY
This paper develops a computational model for determining the total damping coefficient for a unit cell of a MEMS microscale device containing a repetitive pattern of holes. The basic cell of the microstructure is approximated by an axi-symmetric domain and the velocity and pressure fields are determined from solutions of the Navier-Stokes equations using the finite element software package ...

The effects of electric fields on combustion flames have been studied by using several types of experimental techniques as well as few numerical methods. The flame is influenced by the electric field mainly due to the charges present as a result of chemical reactions that take place in the flame. From earlier experiments it was established that the electrical power required to do so is very less ...

A three dimensional COMSOL Multiphysics, transient analysis, diffusion model has been adopted to model the transfers of water in the industrial concrete floors. To take into account the different initial saturation levels at the different levels of the slab, the model is divided into three subdomains. The rise of the waterfront is also simulated and the air overpressure thereby developed at the ...

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 ...
