In the past two decades, highly porous nanostructured materials have been investigated and used for a large variety of applications, such as catalysis, energy conversion/storage, optics, sensing and more. Nanoporous gold (npAu) is one of such materials which have shown great potential as ... 詳細を見る
COMSOL Multiphysics® and the Batteries & Fuel Cells Module are used to create a pseudo 2D model of a Li-ion battery. A sensitivity analysis determines the most sensitive model parameters which are identified by microstructure analysis or optimized by nonlinear least-square regression ... 詳細を見る
The building sector, especially considering existing buildings, requires an enormous part of a country's energy demand. In the course of the renovation of buildings, therefore, less emphasis is placed on the protection of the appearance of historical/older buildings than on their future ... 詳細を見る
The ambient vibrations can be of great promise for harvesting energy initially at small scale to use for micro and nano scale devices. Such vibrations converted to electrical energy by piezoelectric transducer due to their major significance. Various research journals have introduced the ... 詳細を見る
Li-ion battery is being used as power source for various applications. Smart battery diagnostics is essential for creating a better control over the energy storage system and cycle life of a Li-ion battery. It is especially required for real time applications, where more power and energy ... 詳細を見る
Modeling of fractured porous media systems is currently of high interest in various academic and applied fields, mainly in the geological and material sciences. The very different scales of the region of an application case on the larger end and the fracture on the lower end pose a ... 詳細を見る
能量存储技术是减少能量浪费和节约能源的最为有效的手段之一。热化学储能技术具备高功率、大容量和低损耗的特点，在实际应用中可近乎无损耗地进行跨季节性利用，上述优点使得热化学储能近年来吸引了国内外学者的广泛关注。热化学能存储过程涉及流动、传热、传质、反应多个物理过程，为了完成实验室级测试到工业级应用的推广，储能设备的仿真模拟是必不可少的一环。为了简化计算，目前几乎所有的数值研究都假设储能材料的孔隙率为均匀且定常的；但在实际的物理过程中，孔隙率与反应程度紧密相关并随时间和空间变化。本文通过推导建立孔隙率变化的热化学储能模型 ... 詳細を見る
Introduction Self-heating behaviour of dust accumulations is a multiphysics field coupled heat and mass transfer in the porous media. A typical experimental apparatus with a hot storage oven and mesh wire baskets has been taken as the study object. The influence of gas flow velocity, ... 詳細を見る
Mung bean is a good source of protein, vitamins, certain minerals and antioxidant compounds for the vegetarian population of the country. During storage, high moisture content of mung bean leads to the maximum quality and quantity losses due to the growth of fungus and insects. Thus ... 詳細を見る
The time-dependent operation of methanol, ammonia, and urea production units embedded in a steel mill technical environment is analyzed with dynamic simulation models. From different process concepts and gas availability scenarios a set of simulation cases is defined with blast furnace ... 詳細を見る
