Design of latent heat energy storage systems (LHESS) requires knowledge of heat transfer processes within them, as well as the phase change behavior of the phase change material (PCM) use. COMSOL Multiphysics can be used to model (LHESS). Natural convection plays a crucial role during ... Per saperne di più
Vacuum infusion processes are well adapted for large composites parts and, therefore, widely used for the manufacturing purposes in several applications fields such as aviation or naval industry. Simply speaking single plies or a given fibrous reinforcement is pre-shaped and positioned ... Per saperne di più
Hydrogen has great potential to be the fuel of the future through utilization in fuel cells, but it is rarely found naturally and must be produced in energy-intensive processes. Steam reforming, the process of heating natural gas and steam in the presence of a catalyst to drive a ... Per saperne di più
We present a detailed 2D COMSOL Multiphysics® model used to determine and improve the conversion efficiency in a liquid-metal microfluidics-based portable energy transducer. To date, most work on power generation technologies has focused on the optimization of existing technologies, and ... Per saperne di più
In a pumping test the drawdown of the water table in a piezometer is recorded, as response to pumping from a nearby well. Pumping tests belong into the common toolbox of hydro-geologists, used to obtain basic parameters for aquifer characterization. There are various approaches to ... Per saperne di più
Disposal in deep clay geological formations is one of the promising options for disposal of high-level radioactive waste. Yet, they can generate considerable amounts of heat as a side effect of radioactive decay. This paper shows how COMSOL Multiphysics has been used to evaluate the ... Per saperne di più
锂离子电池的充电性能受环境温度影响较大,低温条件下充电极化电压升高充电容量下降的问题一直限制了锂离子电池的发展。本文以电化学反应动力学、质量守恒、电荷守恒和能量守恒为理论基础,利用COMSOL软件建立基于LiFePO4/石墨锂离子电池的电化学-热耦合瞬态计算模型,研究了-5℃、-10℃、-15℃三个低温条件下,锂离子电池充电过程中端电压和正极液相扩散极化电压随SOC的变化规律,并进一步通过提出表征这种极化的变量Pdpe,定量分析了低温条件对正极液相扩散极化的影响,最后通过电解质盐浓度和电解质电流密度分析极化变化的原因 ... Per saperne di più
The conversion of steel mill off-gases to base chemicals is a promising perspective to improve the financial return of steelmaking in Europe and fight CO2 emissions. In the Carbon2Chem® joint research project, mathematical models are developed to simulate operation scenarios of cross ... Per saperne di più
The transport of fluid through nanochannels is of importance in a variety of technological applications, including biological sensing, energy storage and conversion, chemical separation and many others. Synthetic nanofluidic architectures that mimic the gating functions of biological ion ... Per saperne di più
Organic-rich shale resources remain an important source of hydrocarbons considering their substantial contribution to crude oil and natural gas production around the world. Moreover, as part of mitigating the greenhouse gas effects due to the emissions of carbon dioxide (CO2) gas, ... Per saperne di più
