Secondary Flow of Liquid-liquid Two-Phase Fluids in a Pipe Bend

M. Ayala [1], P. Santos [2], G. Hamester [2], O. Ayala [3],
[1] Department of Mechanical Engineering, Universidad de Oriente, Puerto La Cruz, Venezuela
[2] Brazil Scientific Mobility Program, CAPES, Brasilia DF, Brazil
[3] Department of Engineering Technology, Old Dominion University, Norfolk, VA, USA

As the flow passed through the pipe, and entered the bend, various vortical structures appear, meaning that there is a secondary flow emerging. Also while the flow is in the bend gravity forces affect distinctively its behavior as long as the centrifugal force is not greater. From this ... 詳細を見る

A Novel Plug n Play MEMS-Based DNA Microarray

K. Jindal [1], V. Grover [1], B. Nayak [1],
[1] Birla Institute of Technology and Science - Pilani, Ghaziabad, Uttar Pradesh, India

Microarrays are extensively used in modern biology as tools of multiplexed, high throughput analysis to study thousands of genes and their expression inside cells at once [1]. The basic principle of a microarray is quantitative detection of fluorophore tagged DNA. Use of this method ... 詳細を見る

Simulation of Diffuse Optical Tomography using COMSOL Multiphysics®

S. A. M. Kirmani [1] , L. Velmanickam [1], D. Nawarathna [1], S. S. Sherif [2], I. T. Lima Jr. [1],
[1] Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND, USA
[2] Department of Electrical and Computer Engineering, University of Manitoba, Winnipeg, MB, Canada

We show that COMSOL Multiphysics® software can efficiently simulate the diffusion equation (DE) in diffusive optical tomography systems. Using our implementation, we simulate a frequency domain diffusive optical tomography system two order of magnitude faster than the standard Monte ... 詳細を見る

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 ... 詳細を見る

Transformation Optics Simulation Method for Stimulated Brillouin Scattering

R. Zecca [1], P. T. Bowen [1], D. R. Smith [1], S. Larouche [1],
[1] Center for Metamaterials and Integrated Plasmonics and Department of Electrical and Computer Engineering, Duke University, Durham, NC, USA

Stimulated Brillouin scattering (SBS) is a nonlinear phenomenon coupling optical and elastic waves. Traditionally regarded as an undesirable side-effect, it has garnered renewed interest as a platform for investigating slow light, nonreciprocity, and for designing high-performance chip ... 詳細を見る

Simulating Light Propagation during I-PDT of Locally Advanced Head and Neck Cancer

E. Oakley [1], H. Arshad [1], G. Shafirstein [1],
[1] Roswell Park Cancer Institute, Buffalo, NY, USA

Interstitial photodynamic therapy (I-PDT) can be applied for the treatment of locally advanced head and neck squamous cell carcinoma (LA-HNSCC). The complex anatomy of LA-HNSCC requires careful planning of the light delivery and fiber insertion. We have developed an image-based approach, ... 詳細を見る

Advanced Techniques for Predicting Mechanical Product Design via COMSOL Multiphysics® Software

S. Zhuang [1],
[1] CAEaid, Inc., Austin, TX, USA

Mechanical product design is crucial in many engineering field and lots of industries. CAE simulation has been widely applied for predicting virtual product design for a few decades to reduce the cost and shorten the design life cycle. Because of complicated geometry, material ... 詳細を見る

The Use of Finite Element Analysis in the Design of Oil-Water Separators

M. E. Wanas [1], Y. M. Elshazly [1], D. A. ElGayar [1],
[1] Chemical Engineering Department, Faculty of Engineering, University of Alexandria, Alexandria, Egypt

Oil-water separators play an important role in several industries as well as in waste water treatment. However, no basic principles have been set to guarantee the designed separators would work according to the desired efficiency due to the effect various factors. Both time and money ... 詳細を見る
