2D Flow Past a Confined Circular Cylinder with Sinusoidal Ridges
Flow past a circular cylinder arises in many engineering applications, but there is significantly less work studying flow past a cylinder in a confined domain, such as pipe flow or flow in a plane channel. There are many applications where the scaling of a particular problem requires ... En savoir plus
Thermal and Flow Simulation of a High Temperature Printed Circuit Heat Exchanger
Printed circuit heat exchanger (PCHE) is a key component in many energy and power systems, such as concentrated solar power plant, nuclear power plant, aircraft, etc. In this paper, the thermal and fluid performance of a lab-scale PCHE is analyzed using COMSOL Multiphysics® simulation ...

CFD Modeling of a 4-He Evaporation Refrigerator for Polarized Target Experiments
We here present a Computational Fluid Dynamics (CFD) model performed with COMSOL Multiphysics® simulation software as part of a collaboration with the Polarized Target Research Group at the University of New Hampshire (http://nuclear.unh.edu/research/polarized-target-lab/). By coupling ... En savoir plus
Simulating Transport and Adsorption of Organic Contaminants in 3D Porous Activated Carbon Block Media
Granular and powdered activated carbons have been widely used for purification/filtration in air and water as catalysts or organic adsorbents. To obtain mechanical filtration capacity and inorganic reduction performance, activated carbon can be formed as a block-shaped porous media, ... En savoir plus
Chaining Dynamics of a Pair of Ellipsoidal Micro-Particles Under a Uniform Magnetic Field
Due to particle interactions, magnetic particles suspended in non-magnetic fields tend to form chains, clusters or columns under magnetic fields. The non-spherical magnetic particles in the suspension show different rheological properties compared to spherical particles. In this paper, ... En savoir plus
Magnetic Manipulation of Lateral Migration Behavior of a Ferrofluid Droplet in a Plane Poiseuille Flow
This study investigates the effect of a uniform magnetic field on the lateral migration behavior of a ferrofluid droplet in a plane Poiseuille flow at arbitrary directions by means of numerical simulation. A numerical scheme called level set method in combination with the laminar two ... En savoir plus
Comparison of Experimental Measurements with COMSOL Multiphysics® CFD Simulations of Erosional Growth of a Soil Pipe
Soil pipes are large contiguous macropores that exist in soils or geological materials. These macropore features generally serve as conduits for rapid movement of water through soils or geological material, and are generally oriented nearly parallel to the land surface. Soil pipes are ... En savoir plus
Design and Fabrication of Small-Scale Supersonic Wind Tunnel
Introduction: A small-scale supersonic wind tunnel can represent a convenient platform for supersonic flow testing. The scale considered in this work, with maximum cross-sectional area of 1”x1”, requires simpler structure in addition to the low budget costs and minor space ... En savoir plus
Impact of Operating Parameters on Precursor Separation in "Air Hockey" Spatial Atomic Layer Deposition Reactor
A defining characteristic of atomic layer deposition (ALD) is the sequential exposure of a surface to self-limiting, saturating reactions. Temporal ALD operates through intermittent purge cycles, while spatial ALD relies on physical separation accomplished by delivering reactants through ... En savoir plus
Efficiency and Stability Trade-offs in FSI Simulations of Coronary Artery Blood Flow
Some of the most common fluid-structure interaction (FSI) applications in biomedical research include blood flow in the veins and arteries. COMSOL Multiphysics® simulation software offers two main multiphysics schemes for FSI problems: partitioned (segregated) and monolithic (fully ... En savoir plus
