COMSOL Multiphysics® Software Simulation Application for Thermoplastics Viscosity Measurement
Present study discusses a new method of how to apply numerical simulation in COMSOL Multiphysics® software to improve the accuracy of polymer melts viscosity measurements. The main emphasis is placed on evaluating the effects of entrance and exit geometry of a capillary rheometer on ... Read More
Reynolds Number and Geometry Configuration Effect on Secondary Flows in S-Shaped Circular Bends
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
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

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