Temperature Propagation during Cell Stacking Processes for Lithium-Ion Cells
A thermo-physical 3D model of a commercial Li-ion battery was developed and validated. Visualization of the temperature distributions inside a Li-ion cell during cell stacking processes were simulated. Critical temperature levels depend on position, duration and intensity of the thermal ... 詳細を見る
Primary Current Distribution Model for Electrochemical Etching of Silicon through a Circular Opening
Primary current distribution model for anodization of low-doped p-type silicon through a circular opening in frontside insulating mask is developed. The model is applied in two regimes of the process – pore formation and electropolishing – by definition of current density dependent ... 詳細を見る
Heat Generation Modeling of Two Lithium Batteries: from the Cell to the Pack in COMSOL Multiphysics® Software
A thermal model to predict the heat generation during the charge and discharge of a battery pack is an essential tool to manage the thermal behavior, performance and life of the batteries. In this work, a battery cell is modeled in COMSOL Multiphysics® using the Batteries and Fuel Cells ... 詳細を見る
Cooling and Hardening during Injection Molding of Field Joint Coatings for Deep Sea Pipelines
A multilayer polymer coating is applied to carbon steel pipelines installed in the sea to protect against corrosion and to insulate to maintain the temperature. For field joint coatings, both thermosets (like polyurethane) and semi-crystalline thermoplastics (like polypropylene) are ... 詳細を見る
Cycling-Induced Degradation of Batteries
Rechargeable batteries solve electrification and communication problems. As examples, hybrid battery-diesel generator power supplies efficiently power cell towers in remote locations, detached from the power grid. Large battery banks are used to load level user power requirements, ... 詳細を見る
Parameter Estimation in a Single Particle Model Using COMSOL Multiphysics® Software and MATLAB® Optimization
When it comes to study the behavior of the secondary batteries, physics-based models are more representative of the real behaviour than equivalent circuit models, especially for the estimation of the life and capacity fading. On the other hand, the complexity and computational cost of ... 詳細を見る
Numerical Modeling of Alkaline Fuel Cell
A fuel cell is an efficient and clean alternative power source of energy. Alkaline anion exchange membrane (AAEM) fuel cells are one in which conduction of oH- (hydroxyl ion) take place. The advantages of using alkaline fuel cells over proton exchange membrane fuel cells is that ... 詳細を見る
