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

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

A Flow and Transport Model of Catalytic Multi-Pump Systems with Parametric Dependencies

A. Sen [1], D. Myers [1], A. Altemose [1],
[1] Department of Chemistry, Pennsylvania State University, University Park, PA, USA

This poster studies catalytic micropumps and their ability to induce fluid flow on the microscale. The goal of the study is to design a long-distance, directed convective loop. An array of catalytic micropumps was constructed in the domain, comprised of two distinct catalysts in an ... 詳細を見る

Simulation of the Flow of an Autonomous Spherical Ball inside a Pipeline

W. Chalgham [1], A. C. Seibi [1], M. Mokhtari [1],
[1] University of Louisiana at Lafayette, Lafayette, LA, USA

One of the limitations of pipelines performance and structural integrity assessment is the continuous inspection of possible leaks due to corrosion or other types of failure mechanisms. Efforts to develop new technologies started several decades ago where different inspection techniques ... 詳細を見る

Effect of Viscosity of Food on Digestion and Nutrient Absorption in the Human Small Intestine

J. S. Karthikeyan [1], D. Salvi [1], M. V. Karwe [1],
[1] Rutgers University, New Brunswick, NJ, USA

Digestion is the process of breaking down food into smaller components, by mechanical and enzymatic action in the digestive tract, so that the smaller nutrient molecules can be more easily absorbed in the intestinal tract. To study and analyze the human digestive process, different ... 詳細を見る

Sample Preconcentration in Channels with Nonuniform Surface Charge and Thick Electric Double Layers

A. Eden [1], C. McCallum [1], B. Storey [2], C. D. Meinhart [1], S. Pennathur [1],
[1] University of California Santa Barbara, Santa Barbara, CA, USA
[2] Olin College, Needham, MA, USA

We present a novel method for concentrating and focusing small analytes by taking advantage of the nonuniform ion distributions produced by thick electric double layers (EDLs) in nanochannels with heterogeneous surface charge. Specifically, we apply a voltage bias to a gate electrode ... 詳細を見る

Design of a Self-Recharging Untethered Mobile Inspection Tool inside a Pipeline

W. Chalgham [1], A. C. Seibi [1],
[1] University of Louisiana at Lafayette, Lafayette, LA, USA

Pipeline inspection tools present some limitations related to power supply which require recharging after each operation. Using batteries or tethered tools make the duration to inspect any pipeline very limited and time consuming. This paper aims at designing a spherical self-recharging ... 詳細を見る

Simulating Fluid Flow through a Culture Chip for Cell Migration Studies in Microgravity

A. Dhall [1], T. Masiello [1], L. Butt [1], M. Strohmayer [1], M. Hemachandra [1], N. Tokranova [1], J. Castracane [1],
[1] Colleges of Nanoscale Science and Engineering, SUNY Polytechnic Institute, Albany, NY, USA

Exposure to microgravity is known to alter genomic and proteomic expression and suppress immune cell activity. These changes may influence cancer development. Studying cancer cells in this environment, may help uncover novel therapeutic targets. SUNY Polytechnic Institute and ... 詳細を見る

Modeling of Mixing-Sensitive Pharmaceutical Drug Substance Processes in Batch Reactors

F. Akpinar [1], B. Cohen [1], J. Tabora [1], A. Glace [1], K. Lauser [1], F. Lora Gonzalez [1], J. Albrecht [1],
[1] Bristol-Myers Squibb, New Brunswick, NJ, USA

Manufacturing of pharmaceutical drug substances involves chemical unit operations that are dependent on effective mixing, particularly reactions and crystallizations. Poor mixing can cause uneven distribution of chemical species in stirred tanks, leading to impurity formation and ... 詳細を見る

CFD Simulation of Coolant Flow of 2nd Generation HFIR Irradiation Target Holder

J. D'Arrigo [1], A. Elzawawy [1], S. Rabbani [1], J. D. Freels [2]
[1] Vaughn College of Aeronautics and Technology, New York, NY, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA

A 2nd-generation irradiation target holder is being developed at the High Flux Isotope Reactor (HFIR) of Oak Ridge National Laboratory (ORNL). This 2nd-generation holder design is focused on improving the loading and unloading of the targets by the HFIR operators since a large number of ... 詳細を見る
