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 ...

Surface aeration systems are used in the wastewater treatment industry for the transfer of oxygen in the activated sludge process. These systems are capital intensive and also require a significant amount of energy to operate. Scale-up and design of these systems is largely empirical, and due to the size of these systems, modifications for experimental testing can be economically prohibitive. ...
Pranay Goel received his B. Tech. in Engineering Physics from IIT Bombay, and MS and PhD in Physics from the University of Pittsburgh in 2003. He went on to two postodoctoral positions, the first at the Mathematical Biosciences Institute, The Ohio State University, and another at the Laboratory of Biological Modeling, The U.S. National Institutes of Health. He has been with IISER Pune since ...

A Computational Fluid Dynamics study has been performed for a Gas Electron Multiplier (GEM) detector of high energy charged particles, currently under development as part of a new tracker of the high luminosity spectrometers in Hall A at Jefferson Lab. By gradual modifications of the geometry simulated in COMSOL, the design of the frame separating two GEM foils has been optimized with the aim ...

Introduction: The chemical properties of the heaviest elements (atomic number Z > 103) depend on the influence of the high nuclear charge to their electronic structure. Enhanced chemical stability of copernicium (Cn, Z = 112) and flerovium (Fl, Z = 114) was predicted already 40 year ago by Pitzer . The challenge of chemical investigations of these elements is the tiny production rates of few ...

This paper presents a successful step towards the development of a “web-based laboratory” for teaching basic, and even advanced, electromagnetic concepts. The main idea is to develop a reusable model for the student to be used exactly as a hardware experiment in a physical laboratory, where he/she can change some of the experiment\'s physical parameters and get corresponding results. The two ...
Ercan Dede currently works as a Principal Scientist for the Toyota Research Institute of North America, where his research involves the multiphysics simulation and optimization of electromechanical systems for advanced vehicle applications. Dr. Dede received his Ph.D. and B.S., respectively, in 2007 and 1998 in Mechanical Engineering from the University of Michigan. From 1998 to 2003 he ...

Most of mining works, either on the surface or in the underground, demand continuous groundwater pumping in order to operate under dry conditions. When the mining activity stops, dewatering also stops and mining facilities begin to flood, quite quickly at the beginning but becoming slower as the water level in the pit lake rises. The rise of the surface of the lake decelerates due to the bigger ...

COMSOL Multiphysics® has been used to develop assessment tools for the NASA-sponsored Precision Combustion, Inc. (PCI) regenerable Microlith®- based adsorber modules. The Full Scale Water Removal (FSWR) PCI Microlith® was initially modeled for comparison with exit velocity data, measured while exterior canister was removed. Measurement data as well as flow analysis showed that the velocity ...
Evaluation of Performance of Enzymatic Biofuel Cells with Microelectrode Arrays Inside a Blood Artery via Finite Element Approach

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, ...
