Multi-Scale and Multi-Dimensional (MSMD) modeling approaches have been proposed to simulate the thermal, electrical distributions and concentration behaviors of large size pouch cell. This approach is based on coupling of the energy balance with the Newman’s electrode model. Newman’s 1D ... Per saperne di più
With the Creation, roll-out, and maintenance of COMSOL Simulation apps, the role of simulation engineers and departments is expanding to include responsibilities similar to those of software developers. Within our department, we have undergone this transformation and will share the key ... Per saperne di più
Freeze-dried (lyophilized) drug products offer extended shelf life and improved drug stability within a range of combination products including autoinjectors and pre-filled syringes. A key step in the use of combination products is the reconstitution of the freeze-dried drug product (DP) ... Per saperne di più
Vanadium redox flow batteries (VRBs) are a promising new energy storage technology designed for use in long term applications such as uninterruptible power supply and coupling with renewable energy sources (i.e. wind and solar). Crossover is the undesired transport of vanadium ions ... Per saperne di più
Vibration-based Piezoelectric Energy harvesters convert ambient vibration energy into an applicable electrical charge for wireless sensors, IoT applications, and charging the battery, which is most important to range improvement of the Electric Vehicle. This study analyses different ... Per saperne di più
As the global use of COMSOL® apps continues to grow, many developers are seeking practical and secure methods to protect their applications and control their usage. While traditional paid software often relies on license keys, there has been a lack of simple and flexible tools tailored ... Per saperne di più
在所有电池系统中，锂氧电池的理论比能量最高，而实际比能量却明显不足。阻碍氧和/或电子传递导致多孔空气电极的有限利用，而实现对电化学和质量传递耦合的定量理解是具有挑战性的。本文首创了一种具有高度一致和可控通道单元的多孔电极，该电极排除了无序孔隙的随机性，从而能够研究控制机制。通过comsol建立了一个动态非均质模型，提供了LiO2的第一个时空分布，揭示了其在有限电子输运下的反向扩散轨迹。实验和模型的协同结合确定了通道尺寸在分为质量，杂交和电子传递控制的机制中的关键作用。对于大孔隙来说，提高Li2O2的导电性和减轻固液界面损伤比增强氧的扩散更为迫切 ... Per saperne di più
The COMSOL Application Builder can tie a custom user interface to application-specific Java code. This functionality can be used to automatically coordinate changing model characteristics across multiple model nodes. A simple user interface can therefore allow simultaneous ... Per saperne di più
The temperature distributions inside two packs (in-line and staggered) made of large cylindrical lithium iron phosphate cells (of 18 Ah nominal capacity) are analysed in this paper during a 90 A constant discharge current. The analysis of the battery packs temperature distributions is ... Per saperne di più
