Reynolds Number and Geometry Configuration Effect on Secondary Flows in S-Shaped Circular Bends

O. Ayala [1], M. F. Degenring Oliveira [2], P. Loures [2],
[1] Department of Engineering Technology, Old Dominion University, Norfolk, VA, USA
[2] Brazil Scientific Mobility Program, CAPES, Brasilia DF, Brazil

Reynolds Numbers effect: In the first bend, the higher the Reynolds number, the longer the first pair of vorticities stays attached to the wall. In the second bend, the higher Reynolds Numbers, the secondary flow from the first bend dominates. Curvature Radius effect: The smaller the ... Read More

Efficiency of a Vertical Axis Wind Turbine (VAWT) with Airfoil Pitch Control

J. Ma [1], C. Koutsougeras [2], H. Luo [2],
[1] Sam Houston State University, Huntsville, TX, USA
[2] Southeastern Louisiana University, Hammond, LA, USA

In this work, the CFD Module of COMSOL Multiphysics® software is used to study the efficiency of a Vertical Axis Wind Turbine (VAWT) with independently pivoting airfoils so that wind attack angles of these airfoils are adjustable. The work demonstrates how the efficiency of the VAWT is ... Read More

CFD Analysis of a Macroscale Ultrasonic Separator

K. Chitale [1], B. Lipkens [1, 2], W. Presz, Jr. [1],
[1] FloDesign Sonics Inc., Wilbraham, MA, USA
[2] Western New England University, Springfield, MA, USA

Macroscale ultrasonic separation is a new filtration technology, with various applications such as cell clarification, cell therapy, blood-lipid separation, oil-water separation etc. These systems use piezoelectric transducers to create standing waves in fluid-particle mixture. Suspended ... Read More

Simulation of a Dynamic Scraped Surface Heat Exchanger for Non-Newtonian Fluids

S. Birla [1],
[1] ConAgra Foods, Omaha, NE, USA

Scraped surface heat exchangers (SSHEs) are commonly used in the food, chemical, and pharmaceutical industries for heat transfer, crystallization, and other continuous processes. One of the factor posing difficulties to heat transfer is viscosity. Highly viscous fluids tend to generate ... Read More

CFD Simulation of Pore Pressure Oscillation Method to Measure the Permeability of Tight Formations

M. Mokhtari [1], S. A. Madani [1], A. Seibi [1],
[1] Department of Petroleum Engineering, University of Louisiana at Lafayette, Lafayette, LA, USA

Accurate estimation of rock permeability and porosity play a crucial role in the evaluation of oil and gas reservoirs. This evaluation is, however, challenging in tight formations such as shale due to the slow transition of fluid in such formations with extremely-low permeability. To ... Read More

Equation-Based Modeling: Simulation of a Flow with Concentrated Vorticity in an Unbounded Domain

J. M. Russell [1],
[1] Florida Institute of Technology, Melbourne, FL, USA

The velocity field of a fluid flow in an unbounded domain, R, in which the spin of fluid elements is nonzero only within a bounded subdomain, Ri---namely, the interior of a sphere of radius, a---is simulated by equation-based modeling. A change of independent variable motivated by Kelvin ... Read More

Study of Particle Collection Using Magnets

M. D. Cheng [1],
[1] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Airborne particles or aerosols are an unstable system with distributed properties among its individual particulate members. Its fundamental property such as particle size, composition, electrical conductivity, magnetic susceptibility, and morphology could change in response to ... Read More

Modeling the Behavior of a Composite Riser

C. V. Amaechi [1], J. Ye [1],
[1] Lancaster University, Lancaster, United Kingdom

Currently, there are approximately 3,400 deepwater wells in the Gulf of Mexico (GoM) having depths greater than 150 meters, and a worldwide undiscovered deepwater reserves estimated to exceed 200 billion barrels and 25% of the total US reserves (BOEM, 2016), while others are in regions ...

Implementation of Immersed Finite Element Method for Fluid-Structure Interaction Applications

N. Nama [1], T. J. Huang [1], F. Costanzo [1],
[1] Department of Engineering Science and Mechanics, Pennsylvania State University, PA, USA

Fluid-structure interaction (FSI) refers to a class of problems in which the motions of fluid and solid are coupled. FSI is of great significance in many applications such as aero-elasticity, biomechanics, and design of various engineering systems. Typically, the multiphysics involved in ... Read More

A Virtual Laboratory for the 4 Bed Molecular Sieve of the Carbon Dioxide Removal Assembly

R. Coker [1], J. Knox [1], B. O'Connor [1],
[1] Marshall Space Flight Center - NASA, Huntsville, AL, USA

Introduction: Ongoing work to improve water and carbon dioxide separation systems to be used on crewed space vehicles combines sub-scale systems testing and multi-physics simulations. Thus, as part of NASA’s Advanced Exploration Systems (AES) program and the Life Support Systems ... Read More
