Analysis of Cost Effective Vertical Axis Wind Turbine (CEVAWT)

H. Shaikh[1], A. Arjun[1], R. Kumbhar[2]
[1]SVERI's College of Engineering, Pandharpur, Maharashtra, India
[2]WIL Walchandnagar, Pandharpur, Maharashtra, India

Wind turbines are the conventional type of energy source. The main focus of this work is the analysis and fabrication of cost effective VAWT. Cost of the turbine is reduced by low cost material and minimizing its total weight. There are two main types of the wind turbines i.e. Horizontal ... En savoir plus

Air Flow Conditions For Flutter Energy Conversion Device

A. B. Atrah [1]
[1] Universiti Kebangsaan Malaysia, Malaysia

Fluid flow has the potential to provide significant mechanical energy input for electromagnetic energy harvesters. The effect of a bluff body, such as cylinder played a significant role in the creation of a Karman vortex profile in the fluid flow. We study the effect of the number and ... En savoir plus

Developing Solutions to Tonal Noise from Wind Turbines Using COMSOL Multiphysics® Software

J. M. Stauber [1], B. A. Marmo [1],
[1] Xi Engineering Ltd, Edinburgh, United Kingdom

Tonal noise from wind turbines can have effects on neighboring residences and its emission can result in strong regulatory penalties that can include the closure of wind farms. The authors present a model of a new broadband damping approach where containers filled with EniDamp™, an ... En savoir plus

Numerical Model of the Insertion Loss Promoted by the Enclosure of a Sound Source

G. F. Greco [1], I. K. S. Hermont [1], B. P. Murta [1], T. B. Romero [1], P. H. Mareze [1], A. Lenzi [2], J. A. Cordioli [2],
[1] Universidade Federal de Santa Maria, Santa Maria, RS, Brazil
[2] Universidade Federal de Santa Catarina, Florianópolis, SC, Brazil

This study aims to develop and validate a finite element numerical model to represent the Insertion Loss (IL) promoted by the enclosure of a sound source. For the validation, a enclosure prototype was built in wood and the IL was measured in laboratory. The idea is to develop an ... En savoir plus

Quantitative Assessment of Secondary Flows of Single-phase Fluid through Pipe Bends

Z. Kaldy [1], O. Ayala [1],
[1] Department of Engineering Technology, Old Dominion University, Norfolk, VA, USA

Single-phase fluid flow was simulated passing through various three dimensional pipe elbows. The simulations varied by Reynolds number, curvature ratios, and sweep angles and were all conducted using the k-ε model available in COMSOL Multiphysics® software. The intent of this research ...

Multiphysics Simulation of a Printed Circuit Heat Exchanger

A. Daouk [1], O. E. Petel [1], H. Saari [1],
[1] Carleton University, Ottawa, ON, Canada

Compact Heat Exchangers, specifically Printed Circuit Heat Exchangers, are widely used in industry as a replacement for traditionally large heat exchangers (e.g. Shell and Tube) due to their small size and high effectiveness. Modelling of PCHEs, specifically those manufactured by Heatric ... En savoir plus

Validation of a CFD Study of Particle Distribution in Nuclear Workplace

P. Geraldini [1],
[1] Sogin S. p. A., Rome, Italy

Understanding the air flow patterns and aerosol trajectories in ventilated rooms can provide key information for determining where to place early warning and monitoring instruments, and how to minimize hazardous materials in the worker’s breathing zone. The dispersion within rooms can be ... En savoir plus

Calculation of Surface Acoustic Waves on a Piezoelectric Substrate using Amazon™ Cloud Computing

U. Vogel [1], M. Spindler [1], S. Wege [1], T. Gemming [1]
[1] Leibniz Institute for Solid State and Materials, Dresden, Germany

In this work, we seek to simulate SAWs for a better understanding and to benchmark the currently available cloud computing possibilities of COMSOL Multiphysics® software. By using the MEMS module we demonstrate 3D models with reduced geometry to achieve principle information about the ... En savoir plus

Two-Dimensional Numerical Simulation of a Planar Radio-Frequency Atmospheric Pressure Plasma Source

L. Wang [1], G. Dinescu [2], E.- R. Ionita [2], C. Leys [1], A. Y. Nikiforov [1],
[1] Department of Applied Physics, Ghent University, Ghent, Belgium
[2] National Institute of Laser, Plasma and Radiation, Măgurele, Romania

The radio-frequency(RF) plasma sources have shown great potential in various industrial applications such as thin coatings deposition and polymers modification[1,2]. Physics of low pressure RF plasmas has been investigated significantly[3]; however, this kind of plasma source is rarely ... En savoir plus

Fluid Flow During Descemet Membrane Detachment

L. Y. Jiann [1]
[1] Universiti Teknologi Malaysia (UTM), Malaysia

Descemet membrane detachment (DMD) happen when the aqueous humour (AH) in the aqueous chamber flow into the descrement membrance (DM) space through a break and separate the membrane from the stroma. This often happen after the cataract surgery. The fluid is driven by the buoyancy force ... En savoir plus
