Kinetics of Zebrafish Dorsoventral Patterning
The specification of cell types and morphogenesis of many biological systems are regulated by the concentrations of signalling molecules. Many systems employ a pair of secreted short-range activators and long-range inhibitors, and these are widely used to generate complex patterns during ... Read More
Finite Element Convergence for Time-Dependent PDEs with a Point Source in COMSOL 4
Many application problems have non-smooth forcing terms, such as the Dirac delta function. The convergence order for the FEM solution is limited by the regularity of the solution in this case. This paper presents information on the techniques needed in COMSOL 4 to enable FEM convergence ... Read More
Optimization of the Lithium Insertion Cell with Silicon Negative Electrode for Automotive Applications
The US Advanced Battery Consortium (USABC) has established goals for long term commercialization of advanced batteries for electric vehicle applications. In this work, a dual lithium-ion insertion cell with silicon as the negative electrode and an intercalation material as the positive ... Read More
Laminar Fluid Flow and Heat Transfer Studies of an Electrical Conducting Fluid Subject to Combined Electric and Magnetic Fields
The flow of electrically conducting fluids such as liquid metals is significantly affected by applied electric and magnetic fields. The effect has important industrial applications in metallurgy, nuclear technology and other fields. This paper described results of a series of studies ... Read More
Time Domain Analysis of Eddy Currents in Saturating Magnetic Materials
Eddy current phenomena in conducting magnetic media are well understood, although the detailed behavior at high drive levels leading to magnetic saturation are not always well explained. This paper considers the example of an infinite cylindrical magnetic core with an external coil. At ... Read More
Complex Geometry Creation and Turbulent Conjugate Heat Transfer Modeling
The High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) is an 85 MW, light-water moderated, research reactor that operates at low temperature and high pressure. The HFIR is presently scheduled to convert from a high enriched uranium fuel (HEU) to a low enriched ... Read More
Modeling System Dynamics in a MEMS-Based Stirling Cooler
Micro-scale devices based on the Stirling cycle are an attractive choice for chip- and board-level electronics. A new Stirling cycle micro-refrigeration system composed of arrays of silicon MEMS cooling elements has been designed. COMSOL is used to evaluate the thermal performance of ... Read More
Reconstruction for Interstitial Diffuse Optical Tomography (iDOT) for Human Prostate
Determination of tissue optical properties distributions is very important for determining light fluence distribution during photodynamic therapy (PDT). In this study, an interstitial diffuse optical tomography (iDOT) system was used to characterize the spatial distribution of optical ... Read More
Deformation of Biconcave Red Blood Cell in the Dual-Beam Optical Tweezers
A biconcave-shaped Red Blood Cell was trapped and deformed in a dual-trap optical tweezers. The two highly focused trapping beams of Gaussian intensity distribution were modeled as background field in the COMSOL Radio Frequency Module. The 3D radiation stress distribution on the cell ... Read More
Modeling of the Heat Transfer Between a CO2 Sequestration Well and the Surrounding Geological Formation
In a carbon sequestration system CO2 would be pumped down a well and into a reservoir at supercritical temperatures and pressures. An important consideration is the long term stability of the reservoir. The goal of these simulations is to thermally model the injection well and ... Read More
