Simulating Small Molecule Transport Across the Blood-Brain Barrier Using COMSOL Multiphysics®

N. Ramesh1, M.McCloskey1, A. Salminen1, K. Lucas1, J. L. McGrath1
1University of Rochester, Rochester, NY, USA

The blood-brain barrier presents a unique and highly selective semipermeable barrier composed of endothelial and supporting cells. In stressed states, such as during systemic inflammation, the barrier can become “leaky”, increasing in permeability and leading to unwanted solutes from the ... Read More

Simulation of Oil Sands Induction Heating Using Voltage-Driven Coils with Magnetic Core

A. Sherwali1, W.G. Dunford1
1University of British Columbia, Vancouver, British Columbia, Canada

The most common method for in-situ recovery of oil sands is Steam Assisted Gravity Drainage (SAGD). SAGD is based on injecting pressurized steam into the ground to heat up the highly viscous bitumen and reduce its viscosity allowing oil to flow. This process is energy and emissions ... Read More

Direct Optical Surface Roughness Modeling

T. Tran1, S. Peana1, A. V. Kildishev1
1Purdue University, West Lafayette, IN, USA

Optical devices are generally simulated using ideal structures. These ideal geometries are critical in finding major features of the optical response. Unfortunately, fabrication of such devices rarely results in structures that are ideal.[1] In particular, surface roughness is rarely ... Read More

Treating Brain Cancer with Heat Therapy Using a Novel Noninvasive Microwave Applicator

D. B. Rodrigues1, M. Mishra1, J. Molitoris1, Z. Vujaskovic1, P. Turner2, J. Ellsworth2, M. Wadepohl3, G. Futschik3
1University of Maryland School of Medicine, Baltimore, MD, USA
2Pyrexar Medical, Salt Lake City, UT, USA
3Dr. Sennewald Medizintechnik GmbH, Munich, Germany

Heat cancer therapy (HT) involves increasing tumor temperatures to 40-44°C and is a potent radiosensitizer for the treatment of solid tumors, including brain cancer. Current strategies to heat deep-seated targets in the brain are primarily invasive, and existing HT applicators do not ... Read More

Light Management Optimization of Upconversion-Based Solar Cell Using Genetic Algorithms

J. Bork1, M. F. Doty1, J. M. O. Zide1
1University of Delaware, Newark, DE, USA

We demonstrate a COMSOL Multiphysics®-based approach to light management for upconversion-based solar cells (UBSCs). Single-junction solar cells are of high importance to sustainable energy production, however the cells are limited in their performance by the bandgap of the solar cell. ... Read More

Thermomechanical Properties of Elastomeric Stamps for Micro-Transfer Printing Applications

C. Reyes1, K. Oswalt 1, J. Thostenson1, J. Roe1, D. Gomez1
1X-Celeprint, Durham, NC, USA

Micro-transfer printing (MTP) enables mass-transfer of wafer-level chips having lateral dimensions ranging from 3 x 7 um to 650 x 650 um to a nonnative substrate. This is accomplished with an elastomeric stamp containing micrometer scale posts that have been precisely defined using ... Read More

Predictive Model of Landfill Settlement with COMSOL Multiphysics® Employing (THMB) Coupled Processes

M. S. Mousavi1, J. Eun1
1Department of Civil and Environmental Engineering, University of Nebraska-Lincoln

Municipal Solid Waste (MSW) landfills typically experience significant settlement associated with various multi-physical factors such as waste property, placement timing, total height, and environmental conditions such as temperature and saturation throughout the lifetime of the ... Read More

Parametric Analysis and Optimization of an Elastocaloric Heating and Cooling Cycle

S. Nguyen1, R. Warzoha1
1United States Naval Academy, Annapolis, MD, USA

Elastocaloric heating/cooling takes advantage of the structural changes in shape memory alloys (SMAs) that release and absorb heat when a strain is applied over a transition temperature. Heating/cooling cycles that use SMAs offer a potential solution to issues associated with the use of ... Read More

Conductance Modeling of Flexible Organic Thin Film Solar Cell Devices

C. Carradero-Santiago1, J. Vedrine-Pauleus2
1Youngstown State University, Youngstown, Ohio, USA
2University of Puerto Rico at Humacao

In this research work, we developed a virtual model to examine the electrical conductivity of multilayered thin films when positioned above a single layer and multilayers of graphene, and flexible polyethylene terephthalate (PET) substrate. Additional structured thin films were ... Read More

Modeling Ferrofluid Sloshing Vibration Energy Harvesting Using Level-Set Method

N. Anand1, R. Gould1
1North Carolina State University, Raleigh, NC, USA

Ferrofluid sloshing vibration energy harvesters are the recent addition in the domain of vibration energy harvesting systems. These systems are unique in their use of a liquid state transduction mechanism to harvest ambient vibrations/oscillations to generate electric power. In this ... Read More
