Solar drying is a ubiquitous method that has been adopted for many years as a food preservation method. Most of the published articles in the literature provide insight on the performance of solar dryers in service but little information on the dryer construction material selection ... Read More

储氢合金的PCT曲线和氢化动力学性能是描述合金储氢性能的重要标准，目前对合金的PCT曲线测试一般采用体积法，对合金氢化反应动力学的研究一般采用等容差压法。但在实际生产过程中，储氢合金通常是在恒定氢气流速的情况下工作的，所以研究合金在恒定氢气流速条件下的吸氢动力学性能很有必要。与实验相比，采用数值模拟预报合金的吸放氢性能节省了大量的时间和成本，具有突出优势。目前金属Pd及其合金被广泛应用于储氢及氢气纯化等领域，我们通过COMSOL软件建模，构建Pd吸氢热力学与动力学特性模型，选用传热、流体流动、域常微分等物理场模块建立了Pd在恒定氢气流速下吸氢动力学的计算模型 ... Read More

In many groundwater studies, the areal extent of an aquifer is much larger than its thickness so that flow and transport take place primarily in horizontal directions. Thus, the most common type of modeling in practical applications is two-dimensional involving vertically averaged ... Read More

The modeling of ferromagnetic materials is a challenging task of high industrial and academic impact. Thin film and granular systems form the basis of novel spintronic devices such as modern hard drives with a high data area storage density. In order to push the current limits even ... Read More

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 ... Read More

Hydrogen, the most abundant element in the universe, has great potential as an energy source, and can be generated from renewable energy sources. We used COMSOL for the solution of the energy, mass and momentum balance equations that describe the hydrogen absorption and desorption ... Read More

Hydrogen storage in a metal hydride bed, uses an intermetallic alloy that can absorb efficiently high amounts of hydrogen by chemical bonding resulting to metal hydrides. This alloy is capable of absorbing and desorbing hydrogen while maintaining its own structure. The heat, mass and ... Read More

Shielded transportation casks are commonly used for transportation and storage of radioactive waste materials. Design approval of such casks by regulatory authority is subject to its compliance with a thermal test (among other tests) Due to exposure of cask to fire , there is a ... Read More

Biopreservation deals with the protection and storage of complex biologics such as proteins, lipids, and recently, mammalian cells. One preservation method, known as lyopreservation, involves placing a biologic inside a water droplet with some type of sugar excipient (sucrose, trehalose, ... Read More

Wire Electric Discharge Machining (WEDM) is widely used technique for machining intricate geometries. It is a spark erosion, non contact machining process and this gives it an advantage in machining metals irrespective of their hardness [1]. Main process parameters of WEDM are peak ... Read More
