Vertical axis wind turbine has low rotation performance compared with that of horizontal axis wind turbine. This study proposes a new blade shape for vertical axis wind turbine effective for wide range of wind speed. Results obtained from a numerical COMSOL simulation and wind tunnel experiments show the proposed new blade profile has higher performance as compared with conventional blade ...

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., ...

For combustion simulations, the wall temperature and heat transfer is an important piece of information. Coal combustion systems typically have walls that are initially a cast ceramic, but, with time, slag is deposited on the surface and coal and soot are incorporated into the slag. It is this slag coated ceramic that determines the rate at which heat is transferred from the wall combustion ...

The characterization of Li-ion batteries is a relevant topic due to the recent developments in Electric Vehicles (EV’s) and Hybrid Electric Vehicles (HEV’s) applications. In order to manage these devices, accurate models are required. At NEXT ENERGY a two dimensional cell-level thermal model was created based on the discharge characteristics of a cylindrical 18650 secondary Li-ion battery ...

This work investigates the frequency-dependent electrothermal behaviors of freestanding doped-silicon heated microcantilever probes operating under the periodic (ac) Joule heating. The transient heat conduction equation for each component (i.e., the low-doped heater region, the high-doped constriction region, and the high-doped leg region) is solved using the general heat transfer module for DC ...
Modeling and Simulation of High Sensitivity CMOS Pressure Sensor Using Free Boundary Circular Diaphragm Embedded on Ring Channel Shaped MOSFET

Sensors have diverse applications ranging from medical field to space explorations. They convert physical parameters such as temperature, pressure, humidity etc: - into an electrical output. The discovery of piezoresistivity property of silicon and germanium led to miniaturization of pressure sensors. Improvement in the sensitivity is the major factor to be considered while designing pressure ...

A computer simulation model was developed using finite element-based commercial software, COMSOL Multiphysics®, to simulate temperature distributions in wheat samples packed in a rectangular plastic container and treated in a 6 kW, 27.12 MHz RF system with and without mixing conditions. The developed model was then experimentally validated by temperature distributions of three layers without ...

Our inability to record single cell activity with high resolution over a long period of time precludes fundamental understanding of nervous system functions, both under normal and pathological conditions. While the fabrication of current micro- and nano-electrodes has advanced our capabilities to perform long-term recordings, this has been at the expense of signal resolution due to low sealing ...

We describe the thermal modeling of a crate hosting boards with Associative Memories (AM) designed for the Fast Tracker Trigger (FTK) system of the ATLAS detector at the CERN Large Hadron Collider. FTK is a highly paralleled hardware system designed to provide global tracks reconstructed in the inner detector. The hardware system is based on AM for pattern recognition and fast FPGAs for track ...
Effect of Manufacturing Defects in the Form of Internal Leakages on the Acoustic Performance of Mufflers

The presence of manufacturing defects in the form of incomplete welding and missing perforated holes leads to internal leakages in mufflers. This results into unintended acoustic impedance modifications as well as the Herschel-Quincke effect. The narrow region acoustics model of COMSOL Multiphysics® software is used to simulate the thermoviscous losses associated with the leakages. The ...
